However,DO NOTattempt to solve the problemEXACTLY!(we will do that in Part 2) The Simplification Because the optimal collection of items isMUCHmore difficult to determine than a nearly-optimal collection, this kata will only focus on one specific nearly-optimal solution: the greedy solution. The...
In this kind of problem, there are set of items are given with a weight and a value, determine the number of each item included in a collection so that the total weight is less than or equal to the given limit and the total value is as large as possible....

The method to process node j that exploits the multi-follower formulation for the robust counterpart of the lower-level problem is formally stated in Algorithm 2. In contrast to the approach using the extended formulation, in which a single cut is added at each node of the branch-and-cut se...
As we will see in Section 2.2, using a unitary scaling factor decidedly simplifies the problem. In the rest of this explanation, we will consider, for simplicity, this unit-cost case. The most straightforward method to build the credible set is perhaps to follow a greedy approach which ...
Greedy algorithmThe Quadratic Knapsack Problem (QKP) involves selecting a subset of elements that maximizes the sum of pairwise and singleton utilities without exceeding a given budget. The pairwise utilities are nonnegative, the singleton utilities may be positive, negative, or zero, and the node...

Given a set of profitable items where each item is a set of weighted elements, the Set-union Knapsack Problem is to pack a subset of items into a capacity constrained knapsack to maximize the total profit of the selected items. This problem appears in many practical applications; however, it...
Separation problem (8) is a LP problem, where each row of the constraint matrix is a feasible solution of the knapsack problem. Even for low-dimensional problems, one can hardly enumerate all the feasible points. Row generation method is an iterative approach where, at each iteration, a parti...
