Coati Optimization Algorithm

The algorithm maps foraging, climbing, and predator-avoidance behaviors to different ways of changing candidate solutions. These modeled actions encourage movement through unexplored regions while also directing some candidates toward better solutions or away from unpromising areas. This behavioral structure gives the search process multiple mechanisms for investigating and refining engineering designs.

Exploration examines diverse regions of the search space, reducing the chance that the algorithm settles too early on a limited area. Exploitation concentrates updates around promising solutions to improve them through local refinement. Alternating or combining these tendencies helps address engineering problems in which broad search and precise improvement are both necessary for useful results.

Each coati represents one possible engineering design, so its position encodes the values of the problem's decision variables. That representation can accommodate continuous variables, discrete choices, or constrained designs, depending on the optimization task. The position updates therefore operate directly on candidate design configurations rather than requiring a conventional closed-form solution.

Nonlinear and multimodal problems can contain complicated relationships among variables and multiple competing regions of promising solutions. The algorithm's population-based search examines several candidate solutions instead of following one deterministic path, while its exploration and exploitation behaviors support both region discovery and local improvement. This makes it useful when conventional mathematical methods struggle with the search space.

First, define the engineering objective, decision variables, and any constraints. Next, represent a population of candidate designs as coati positions and evaluate their quality. The algorithm then updates those positions using behavior-based exploration and exploitation, repeatedly reassesses the candidates, and retains the most promising design identified during the search.

The method can support structural design, energy-system optimization, control-parameter tuning, and scheduling. In each case, candidate solutions encode alternative designs, operating settings, or task arrangements, while the objective evaluation identifies their relative quality. Its broader value appears when the engineering problem has nonlinear, multimodal, poorly defined, or mixed decision spaces that are difficult to optimize conventionally.
