Meet the concept

↗

A linear program is characterized by having an affine objective function and linear constraints. This specific structure distinguishes it from other optimization models like least-squares fitting.

Conditions: The optimization problem is a linear program.; The objective function is affine.; The constraints are linear.

Least-squares fitting differs from linear programming by minimizing a squared residual norm, whereas linear programs have affine objectives. This distinction highlights different model structures within optimization.

Conditions: The problem is a least-squares fitting task.; The comparison is with linear programming.; The objective involves residuals.
