A Radial Memetic Algorithm to Resolve the No-Wait Job-Shop Scheduling Problem

Mathematics
A new radial memetic algorithm is proposed to resolve the no-wait job-shop scheduling problem. Basically, each sequencing solution is factorized as a distance-based ranking model, i.e., each solution is decomposed in n − 1 terms, where n is the number of
