How to solve the cutting stock problem?
Starting from a base set of cutting patterns, solve the linear programming problem of minimizing the number of logs used subject to the constraint that the cuts, using the existing patterns, satisfy the demands. After solving that problem, generate a new pattern by solving an integer linear programming subproblem.
