A column and constraint generation algorithm for the dynamic knapsack problem with stochastic item sizesWe consider a version of the knapsack problem in which an item size is random and revealed only when the decision maker attempts to insert it. After every successful insertion the decision maker ...

In order to solve the model exactly for a given partition, a column-and-constraint generation algorithm is proposed. In addition, a scenario partitioning algorithm to enable the risk level of the model to be close to a given target is devised, and partitioning schemes for combining it with ...

A column-and-constraint generation algorithm In this section, we present another cutting plane procedure to solve two-stage RO problems. Because the generated cutting planes are defined by a set of created recourse decision variables in the forms of constraints of the recourse problem, the whole ...
