Solving the Knapsack Problem - A Guide to Dynamic Programming |
https://dev.to/k1lgor/solving-the-knapsack-problem-a-guide-to-dynamic-programming-50h0

Solving the Knapsack Problem A Guide to Dynamic Programming IntroductionThe Knapsack problem is a well known optimization problem in computer science Given a set of items each with a weight and a value the problem is to select a subset of the items that maximizes the total value while keeping the total weight below a certain limit The problem gets its name from the idea of packing a knapsack with items of varying sizes and values The Knapsack problem is a classic example of a dynamic programming problem which means that we can solve it efficiently by breaking it down into smaller subproblems and combining the solutions to those subproblems to find the optimal solution Dynamic Programming SolutionThe key idea behind the dynamic programming solution to the Knapsack problem is to build a table often called a DP table where each cell represents the optimal value for a particular combination of items and weights The table is initialized with zeros and then filled in using a recursive formula In the recursive formula we consider each item in turn and for each item we consider all possible weights up to the maximum weight If the weight of the current item is greater than the current weight we cannot include the item so we simply use the value from the previous row in the table If the weight of the current item is less than or equal to the current weight we have a choice we can either include the item in which case we add its value to the value of the optimal solution for the remaining weight or we can exclude the item in which case we simply use the value from the previous row in the table After filling in the entire table we can use it to backtrack and find the selected items that give us the maximum value Starting from the bottom right corner of the table we check each cell to see if its value is different from the value in the cell above it If it is that means we included the item corresponding to that row in the optimal solution so we add it to our list of selected items and move to the cell in the previous row with the remaining weight The Python ImplementationHere is a Python implementation of the Knapsack algorithm using dynamic programming def knapsack items max weight Initialize a D array with zeros dp table for in range max weight for in range len items Fill the table with the optimal values for each weight and item combination for i in range len items weight value items i for w in range max weight if weight gt w dp table i w dp table i w else dp table i w max dp table i w dp table i w weight value Backtrack to find the selected items selected items w max weight for i in range len items if dp table i w dp table i w selected items append items i w items i Return the total value and selected items return dp table selected itemsdef main items max weight total value selected items knapsack items max weight print Total value total value print Selected items selected items if name main main The knapsack function takes two arguments a list of items where each item is represented as a tuple of the form weight value and a maximum weight The function returns a tuple containing the total value of the selected items and the list of selected items themselves We have four items with weight and values and We want to find the subset of items that maximizes the total value while keeping the total weight below Running the knapsack function with these arguments gives us the following output Total value Selected items This means that the optimal subset of items has a total value of and consists of the items with weight and values and ConclusionThe Knapsack problem is a classic optimization problem that can be efficiently solved using dynamic programming The key idea is to build a table that represents the optimal value for each combination of items and weights and then fill it in using a recursive formula The resulting table can be used to backtrack and find the selected items that give us the maximum value In this article I have shown how to implement the Knapsack algorithm in Python using dynamic programming and provided an example of how to use it While this implementation is relatively simple there are many variations of the Knapsack problem with different constraints and objectives and more sophisticated algorithms may be needed to solve them efficiently Thank you for reading Stay tuned for more ️and logout |

The best smart displays you can buy |
https://www.engadget.com/best-smart-display-202448797.html?src=rss
|
The best smart displays you can buy Smart displays have evolved quite a bit since the initial debut of Amazon s first Echo Show back in In fact the category didn t really come into its own until Google joined the fray with its own line of hardware about a year later Now both of these companies are essentially dominating the smart display landscape with each offering their own take on a smart assistant with a screen It s that screen that makes smart displays so much more useful than smart speakers Rather than just having a voice recite the current weather report for example you can see a five day forecast as well The same goes for when you ask about your shopping list or calendar it s simply easier to see the whole list or your day s appointments at a glance Plus displays offer other benefits that speakers can t like watching videos or checking your webcam to see who s at your front door They re especially handy in the kitchen where you can use them for step by step cooking instructions And thanks to touchscreens you can often navigate through functions and settings a lot faster than using your voice Amazon vs GoogleThe first question you should ask is when looking for the best smart display for you is whether you prefer Amazon s or Google s ecosystem If you have a lot of Google products in your home like Nest thermostats or Nest cams then a Google powered model makes more sense If you have Amazon products like a Fire TV Stick or a Ring cam Amazon would obviously be a better choice Of course it s perfectly acceptable to have products from competing companies in the same home but just realize they might not work seamlessly with each other Aside from that the two systems also offer some unique features Google for example works best if you have an existing Google account and use services like Calendar and Photos In fact we especially love Google smart displays because they work well as digital photo frames You can set it up to automatically pull in pictures of friends and family from your Google Photos library and the algorithm is smart enough to use what it thinks are the best shots ーso less chance of blurry photos or images of your eyes half closed showing up for example It might seem like a minor point but seeing as the display is on standby percent of the time its secondary function as a digital photo frame is very welcome All Google smart displays also support YouTube and YouTube TV step by step cooking instructions and all of the usual benefits of Google Assistant like weather reports As with Assistant on the phone it also has voice recognition so only you can see your calendar appointments and not others Amazon s smart displays on the other hand are slightly different Instead of YouTube they offer some alternative video streaming options including Amazon Prime NBC and Hulu They also come with two browsers Silk and Firefox which you can use to search the web or watch YouTube videos a handy enough workaround given the lack of a dedicated app Amazon devices offer step by step cooking instructions as well thanks to collaborations with sources like SideChef and AllRecipes In fact the cooking instructions sometimes include short video clips But although you can use Amazon s displays as digital photo frames the process is not quite as intuitive as Google s and Amazon doesn t have anything comparable to Google s photo sorting algorithm The best smart displaysSmart displays come in all sorts of shapes and sizes and some are better suited to certain rooms in the home than others So while we do have some favorite all around picks we ve also compiled a list of the best smart displays that would suit specific use cases as well The best Google smart display Google Nest HubWe at Engadget tend to prefer Google smart displays because most people are likely already entrenched in the Google ecosystem due to the ubiquity of Google services like Gmail Calendar and so forth We also tend to find Google Assistant to be a little smarter than Alexa especially when bringing up answers from the web As mentioned earlier we also really like the tie in with Google Photos and the smart photo sorting algorithm Our favorite smart display overall is Google s latest Nest Hub Its inch size is a better fit in more rooms and its unobtrusive design combined with its soft fabric exterior blends nicely into your existing home decor It does everything we think most people would want in a smart display like YouTube videos step by step cooking instructions smart home controls and the ability to check in on your Nest cams if you have any In fact the Nest Hub is especially useful if you have a Nest video doorbell as the camera view of who s at the front door will show up on the screen An ambient light sensor helps to detect the light and color temperature of the environment and adjusts the screen to match Plus if you choose it can help track your sleep patterns if placed next to your bed Another feature of the Nest Hub is actually a lack of one It doesn t have a camera That gives it that additional layer of privacy that many people covet and it s also a lot more suitable for personal spaces like the bedroom Sure you could also cover up a camera with a shutter but with the Nest Hub you don t have to remember to do that Runner up Google Nest Hub MaxIf you like Google but you miss having a camera for video calls or you just prefer a bigger screen consider the Google Nest Hub Max At inches instead of seven it works a lot better for watching videos from YouTube and YouTube TV It s especially useful in the kitchen where it functions as a kind of portable television and you can see more of those step by step cooking instructions at a glance The bigger display also means a larger photo frame which you may prefer As mentioned the Nest Hub Max adds a camera to the mix It doesn t have a physical shutter which is a concern but you can shut it off with an electronic switch You can use the camera for video calls with Google s Duo service as well as Zoom and it can also function as a Nest Cam to help you keep an eye on your house when you re away Another benefit of the camera is the addition of Face Match facial recognition for authentication purposes which we found to be a little more accurate than just using Voice Match Last but not least the Nest Hub Max s camera adds a unique gestures feature that lets you play and pause media simply by holding up your hand to the screen It s not entirely necessary but it s potentially useful if you re in a noisy environment and just want the music to stop without having to shout over everyone Or perhaps you have messy hands while cooking and don t want to dirty up the display The best Amazon smart display Amazon Echo Show Our favorite Amazon smart display is the second gen Echo Show Its inch screen is just right it doesn t take up as much space as the Echo Show but it s also more suitable for watching videos than the tiny Echo Show Like other Amazon smart displays it has a built in camera but there is a physical camera cover to help alleviate privacy concerns As such the Echo Show is a compelling choice if you want the option of using your smart display for video calls Not only is the camera quality fantastic but the Show has a feature that automatically frames your face and follows your movements during video calls It s useful if you want to move around as you re chatting or if you have rambunctious children and pets running around the house and you want to involve them in the conversation You can use the Echo Show to make calls between other Echo Show displays or through Skype or Zoom As with the other smart displays the Echo Show also works as a digital photo frame and can be used to keep up with the news check the weather and control smart home devices If you want to use your smart display to play music we also really like the Echo Show s audio quality on account of its deep bass and rich tone Runner up Amazon Echo Show At only inches wide the Echo Show is one of the smallest smart displays on the market and as a result will work nicely on a desk or a nightstand In fact one of the reasons we like the Echo Show so much is that it doubles as a stellar smart alarm clock It has an ambient light sensor that adjusts the screen s brightness automatically a tap to snooze function so you can whack the top of it for a few extra minutes of shut eye plus a sunrise alarm that slowly brightens the screen to wake you up gently The Echo Show does have a camera which might make you a touch queasy if you are privacy conscious especially if this is supposed to sit by your bedside Still it does have a physical camera cover which can help ease any fears Best smart clock Lenovo Smart Clock Perhaps a smart display doesn t appeal to you because you don t care about watching videos on it But maybe the idea of a smarter alarm clock like the Echo Show intrigues you In that case I d recommend the inch Lenovo Smart Clock which isn t a full fledged smart display because you can t play any videos on it but it does use Google s smart display tech so you can use it for controlling your smart home as well as checking out your Nest Cams We also like it because it lacks a camera which makes it perfect for your nightstand It has all of the features we want in a smart alarm clock like an ambient light sensor that tap to snooze function and a sunrise alarm Plus the latest version can double as a night light you can swipe down the display to enable it and you can get an optional wireless charging base to go with it If the Smart Clock is too advanced for you Lenovo does offer an even simpler version called the Smart Clock Essential It really isn t a smart display at all it s really more of a smart speaker with a clock but it does perform many of the same functions as the Smart Clock Lenovo sells the Smart Clock Essential in two different versions One has Google Assistant while the other is powered by Alexa The one with Google Assistant has a built in night light an extra USB port for charging devices and a mic mute button The one with Alexa on the other hand is compatible with an optional docking station that can be used with accessories such as a wireless charging pad or an ambient light dock it comes in either a sea lion or a squid shape that can act as a night light This article originally appeared on Engadget at |
