Algorithms for the circular open dimension problem.

In this paper, we propose three algorithms for approximately solving the circular open dimension problem, known also as the circular strip cutting/ packing problem. We first propose an open strip generation solution procedure that uses the best local position rule into the open strip. Second, we propose a simple augmented version of the first algorithm by introducing an exchange-order strategy. Third, we propose a hybrid algorithm that combines beam search and a series of target values belonging to a predetermined interval search. We evaluate the performance of these algorithms on several instances varying from small to large ones. Encouraging results have been obtained.
