Abstract :
This paper proposes a new Evolutionary Algorithm for the Dynamic Resource Constrained Project Scheduling Problem. This algorithm has new features that get around some problems like premature convergence and other ones. The indirect representation approach was used because it allows the construction of a feasible solution from any input priorities. A parallel version is also proposed, making good use of multicore processors available nowadays. The results of sequential and parallel versions were very significant, improving in almost all ways the best results present in literature.
