      Analysis

      This paper addresses a strongly NP-hard scheduling problem, proposing both a Constraint Programming (CP) model and a Biased Random-Key Genetic Algorithm (BRKGA) to minimize makespan. The significance lies in the combination of these approaches, leveraging the strengths of both CP for exact solutions (given sufficient time) and BRKGA for efficient exploration of the solution space, especially for larger instances. The paper also highlights the importance of specific components within the BRKGA, such as shake and local search, for improved performance.
      Reference

      The BRKGA can efficiently explore the problem solution space, providing high-quality approximate solutions within low computational times.
