Labs

The goal of the labs is to exercise the topics presented on lectures.

On some labs you will receive homework assignment, which are implementation of an algorithm or a method solving some interesting combinatorial optimization problem. In all cases, the solutions to homework assignments are submitted to Brute where they are automatically checked and evaluated. Late upload will be penalized by -1 point for each week after deadline. Completing all homeworks successfully (i.e., the output is classified as correct according to Brute) is a mandatory requirement for the assessment. Moreover, we encourage you to solve the homeworks since in the practical test you will use algorithms implemented for the homeworks.

NOTE: There is GUROBI 9 in Brute. Features highlighted in release notes of version 10 are not available.
