Assignment of attributes to elements subject to constraints is achieved using a system that has a systematic engine and a nonsystematic engine. The systematic engine includes a schedule developer for producing partial proposed assignments, a pruning processor for determining violations of discrepancy limits by a partial proposed assignment, and a bound selector for relaxing discrepancy limits as needed. The non-systematic engine includes a schedule packer for modifying assignments proposed by the systematic engine and an evaluator for comparing the modified assignments with the constraints.
