Heuristic parameters.

Solution procedure	Heuristic parameters
SVRC1	𝛿=0.1
SVRC2	𝛿=0
SSA1	neigsize = [0.45 0.45 0.1 size (PS, 1)]	𝑇𝑜=1×10^5	𝛼=0.8	Accep/MaxTrials = 30	MaxChains = 3
SSA2	neigsize = [0.1 size (PS, 1)]; neigsize == [0.3 size (PS, 1)]; for 8×8×10, classes II and III	𝑇𝑜=1×10^5	𝛼=0.8	Accep/MaxTrials = 30; 50 for 8×8×10 class I; and 80 for classes II and III	MaxChains = 2
SSA3	neigsize = [222]; neigsize == [333]; for 8×8×10, classes II and III	𝑇𝑜=1×10^5	𝛼=0.8	Accep/MaxTrials = 30; 50 for 8×8×10 class I; and 80 for classes II and III	MaxChains = 2
SGA1	pm = 0.01	pc = 0.95	gen = 20	pop = 20% of PS
SGA2	pm = 0.01	pc = 0.95	gen = 10	pop = 10% of PS
SGA3	pm = 0.01	pc = 0.95	gen = 10	pop = 10% of PS

Note: for the 35×20×35 size, SGA2 and SGA3 have gen = 25 and pop = 120 individuals. The number of runs was decreased from 5 to 3.
