Objective measures

Definition

Objective measures refer to quantifiable and unbiased metrics used to evaluate the performance or effectiveness of a system, often based on specific criteria or benchmarks. These measures are crucial in designing effective fitness functions, as they ensure that the evaluation process is clear, consistent, and free from subjective influences, allowing for an accurate assessment of a robotic system's capabilities and behaviors.
