But if the following constraint is imposed... how do I solve the question? If you choose some item 'U' you won't be able to choose another item 'V'. For example Items are given as [Name, Weight, Value] Items are : A 10 20 B 50 80 C 20 30 D 30 70 E 50 50. If you choose B then you cannot …
WebBesides, Chang [18] employed a couple of binary numbers to represent the relationship among binary variables, which became the first generalized algorithm concerning fuzzy programming with piecewise linear membership functions. However, in some cases the utilization of binary variables would lead to constraint-free problems.
