GRASP for Low Autocorrelated Binary Sequences

The search for low autocorrelated binary sequences(LABS) is a combinatorial optimization problem, which is NP-hard. In this paper, we apply Greedy Randomized Adaptive Search Procedures (GRASP) to tackle the LABS problem. The algorithm is capable of systematically recovering best-known solutions reported by now. Furthermore, it can find out good autocorrelated binary sequences sequences in considerably less time as comparison with other heuristic methods.
