Key Concepts

Local Minimum

A local minimum is a point where a function's value is lower than that of its neighboring points, but not necessarily the lowest across the entire domain. This can occur in situations where a function has several valleys, where each valley contains a point that is lower than its immediate surroundings, yet some valleys may have points with even lower values. Understanding local minima is important in scenarios where algorithms are used to optimize functions that may have multiple such minima.

Absolute Minimum

An absolute minimum, also known as a global minimum, is the point at which a function achieves its lowest possible value over its entire domain. This means that regardless of the location within the overall space, no other point yields a lower function value. It is a critical concept in optimization, indicating the optimal solution when considering all potential outcomes.
