Definitions:

Optimal Solution

The most efficient, cost-effective, or achievable outcome within a given set of constraints and conditions.

Constraints

Limitations or conditions that must be followed or satisfied within problem-solving or optimization processes.

Linear Optimization Models

Mathematical models that optimize (maximize or minimize) a linear objective function, subject to a set of linear constraints.

Basic Solver

An optimization algorithm tool used in mathematical programming and operations research to find an optimal solution by varying multiple inputs within given constraints.
