# Solving Knapsack Problem

That is to say, the program above computes more than expected because that the weight changes from 0 to W all the time.All we need to do is to compare m[i-1, j] and m[i-1, j-w[i v[i] for m[i, j], and when m[i-1, j-w[i]] is out of range, we just give the value of m[i-1, j] to m[i, j].However, on tests with a heterogeneous distribution of point values, it is more difficult to provide choices.Feuerman and Weiss proposed a system in which students are given a heterogeneous test with a total of 125 possible points.Now let's say we want to know the prefix sum up to element 5. Do we need to loop over them all again for each one?

It's one of the most well studied combinatorial optimization problems and a popular introduction to dynamic programming.One theme in research literature is to identify what the "hard" instances of the knapsack problem look like, The goal in finding these "hard" instances is for their use in public key cryptography systems, such as the Merkle-Hellman knapsack cryptosystem.Several algorithms are available to solve knapsack problems, based on dynamic programming approach, items and the related maximum value previously, we just compare them to each other and get the maximum value ultimately and we are done.

On the verge of writing a research paper, you should prepare an introduction.
