Listing 1. Iteration over a sorted binary tree using recursive descent in an enumeration method. public interface KeyValueTask { void apply(String key, String value ...

A timetabling problem is formulated as a large integer linear programming problem in 0-1 variables. A solution method based on Lagrangean relaxation coupled with subgradient optimization is presented.

Integer programming, a cornerstone of combinatorial optimisation, focuses on the selection of discrete decision variables to solve complex real‐world problems such as scheduling, network design and ...
