The Pareto front is the curve that links all non-dominated solutions in the objective-value plot. Visually, it is the lower-left boundary of the attainable set in this minimization problem, representing the best possible trade-offs between the conflicting objectives.

Conditions: Objectives are plotted in the (OBJ_1, OBJ_2) plane.; The example uses minimization of both objectives.

The purple curve represents the trade-off curve in the objective space. It is formed by mapping the optimal solutions obtained as the weight w1w_1 changes, showing how improving one objective comes at the expense of the other.

Conditions: At least two objectives are plotted against each other.; Solutions are generated for multiple weight values.
