Question

In an all-integer linear program, _________.
a. all decision variables must be integer.
b. all objective function coefficients and right-hand side values must be integer.
c. all right-hand side values must be integer.
d. None of the provided answers is correct
e. all objective function coefficients must be integer.

Answer 1

Answer:

The option a) all decision variables must be integer is correct.

In an all-integer linear program , all decision variables must be integer.

Step-by-step explanation:

In an all-integer linear program , all decision variables must be integer.

Because :

• In a integer linear program there are two main reasons for using integer variables while modeling problems .
• The integer variables represent only the quantities if it is an integer.
• The integer variables represent decisions variables and therefore should only take on the value 0 or 1.

Therefore option a) all decision variables must be integer is correct.
