Question

Quizplus · Accepted Answer

A conditional constraint is a constraint involving binary variables that does not allow certain variables to equal one unless certain other variables are equal to one. Therefore, option A is the correct choice. Corequisite constraint refers to a constraint that requires two or more variables to be equal to one simultaneously. K out of n alternatives constraint requires a certain number of binary variables to be equal to one out of a group of n variables. Mutually exclusive constraint specifies that only one binary variable can be equal to one out of a group of two or more variables.
