0/1 knapsack problem is a classical dynamic programming model. There is a knapsack with the capacity of m, you should find the maximum volume can be filled in. Still, we need: DP memory and the representation The initialization of DP memory DP formula Return value. DP memory and the repre...
We consider a special case of the unbounded knapsack problem that is characterized by a set of simple inequalities that relate item weights to item costs. We present an algorithm for this special case with time complexity linear in the number of items. ...

Owing to the problem of solving the time complexity by traditional exponential is too complicated, turned it into the other problem which is relatively easy, then solving polynomial time wih quantum computer, which can Reduce the difficulty of solving the problem. Analysised of the complexity of ...
Computer science assigns computational problems to complexity classes, which are sets of functions that can be computed within given resource bounds16. Resource constraints of particular interest are time and memory. The problem of finding the solution to the 0–1 KP is a member of the complexit...
KNAPSACK PROBLEMA systolic algorithm for solving the O/1-knapsack problems with n items is presented. The computational model used is a tree structure which consists of 2(n) identical processing elements (PEs). Each PE executes the same program at any time step. The time complexity varies ...
