Which is a knapsack problem with 3 constraints. + mass_n * y_n) //The case where you are minimizing mass This Modification CAN Be Used In A Minecraft Modpack. After Inventory Is Closed Items Are Saved In That Knapsack. The Portable Knapsack Has 27 Input/Container Slots. The Traveler's Backpack addon adds 4 new backpacks to your game, unlike most addons these backpacks are blocks instead of entities and you can put it on your back without removing the chestplate which can help a lot in your adventures The traveler's Backpack has more than one use, in addition to carrying items it can also be used as a bed. Let y_i be a binary variable, where y_i is one if and only if the item is NOT in the knapsack. The Leather Knapsack Is Crafted By 8 Leather In The Crafting Table With A Golden Nugget In The Center. Then you get an equivalent problem on the form: let mass_i be the mass of item i, let vol_i the volume, and let val_i be its value. + val_n * x_n >= MinValueĪ trick you can use to to make it more "knapsacky" is to substitute x_i with 1-y_i, where y_i is 1 one, if and only if item i is not in the knapsack. + mass_n * x_n) //The case where you are minimizing mass Let x_i be a binary variable, where x_i is one if and only if the item is in the knapsack. If I understand your question correctly, the problem you wish to solve is on the form: let mass_i be the mass of item i, let vol_i the volume, and let val_i be its value. ), so you only need to keep the previous and current "rows" of the DP matrix. You can save space (and possibly time, although not in the asymptotic sense) by calculating it in bottom-up fashion - this would bring the space complexity down to O(c), since while calculating f(i.
Memoising this gives a pseudopolynomial O(nc)-time, O(nc)-space algorithm, where n is the number of items and c is the value threshold. To calculate f(i, j), we can either include the ith item or not in the knapsack, so f(i>0, j>0) = min(g(i, j), h(i, j)) # Can include or exclude ith item pick the bestį(_, 0) = 0 # Don't need any capacity to reach value of 0į(i0) = infinity # Can't get a positive value with j. Order the items arbitrarily, and define f(i, j) to be the minimum possible capacity of a knapsack that holds a subset of the first i items totalling at least a value of j. Let's call the weight of item i w(i), and its value v(i).
