Question

an example of a solver constraint is to specify that a variable cannot be solved to zero.

true

false

Explanation:

Analyze the definition of Solver constraints

In optimization tools like Excel Solver, constraints are conditions that must be satisfied by the solution. Common constraints include restricting variables to be integers, binary, non-negative (\(\ge 0\)), or equal/less/greater than specific values.

Evaluate the specific statement

The statement claims that "a variable cannot be solved to zero" is an example of a solver constraint. While you can constrain a variable to be non-zero (e.g., \(x \ge 0.0001\) or \(x
e 0\)), "cannot be solved to zero" is not a standard built-in constraint type, and Solver typically allows variables to be zero unless explicitly restricted otherwise. More importantly, standard linear programming and Solver models frequently use non-negativity constraints (\(x \ge 0\)) which explicitly allow variables to be zero. Thus, the statement is conceptually false.

Answer:

• True
• False (Correct answer)
