Discrete symbiotic organisms search method for solving large-scale time-cost trade-off problem in construction scheduling

作者：

Highlights：

• A novel discrete symbiotic organisms search method is presented for the large-scale DCOPs.

• Network-based heuristic parasitism operator is designed to advance the exploration ability.

• DSOS achieves better or close performance comparing to the state-of-the art methods.

• High quality solutions are achieved for new large-scale project instances of real-life complexity.
