# Parameter Objective

## About this Block

**What it does:** The **Parameter Objective** block defines the goal of an optimization run. It takes a Goal (either Minimize or Maximize) and a Parameter to set the objective function. The optimizer then uses this objective to guide its search for an optimal solution.

**Common uses:**

* Finding the lightest possible design that meets all structural requirements.
* Maximizing a component's stiffness while keeping its mass below a certain limit.
* Optimizing a part's geometry to improve its performance under various conditions.

**Tips:**

* The *Goal* input determines whether the optimizer will try to increase or decrease the value of the parameter.
* The *Parameter* input must be a scalar optimization parameter whose value can be calculated for each design iteration.

***

Specifies a goal for a Parameter Optimization by indicating a Parameter to minimize or maximize. Guides the optimizer toward the desired outcome.
