WebApr 10, 2024 · Table 27 shows that the solutions calculated by using PGSA, GA, GP, and Tribes are infeasible as they violate the imposed constraints. It is also shown in Table 27 that the optimal value of parameters found by using the AOA-NM algorithm is better than AOA, ABC, PSO, SA, and TLBO, with the least number of function evaluations of 4000. Webjudge the solution information in the prob lem context is essential. Infeasible Models Greenberg [1993a, b, c] and Chinneck [1997] describe procedures one can use to discover the PS causing infeasible models.
