Ant Colony Optimization Algorithm Quiz

A probabilistic technique for finding good paths through graphs in computational problems.

Multi-agent methods inspired by the behavior of real ants.

Real ants lay down pheromones, and simulated 'ants' record their positions and the quality of their solutions.

<p>Derivative-free optimization is a discipline in mathematical optimization that does not use derivative information to find optimal solutions. It is used when derivative information of the objective function is unavailable, unreliable, or impractical to obtain.</p> Signup and view all the answers

<p>The objective of derivative-free optimization is to numerically optimize an objective function f : A → R for some set A, by finding x0 ∈ A such that f(x0) ≤ f(x) for all x ∈ A.</p> Signup and view all the answers
