Optimisation inspired by nature
Natural algorithms — also called nature-inspired or bio-inspired algorithms — are computational methods that mimic processes observed in the natural world. Rather than solving problems through brute force, they iteratively evolve, search, and improve candidate solutions in ways modelled on evolution, collective insect behaviour, thermodynamic cooling, and murmuration dynamics.
These metaheuristics are particularly powerful for problems where the search space is too large for exhaustive search, where the fitness landscape has many local optima, or where gradient information is unavailable. They are widely used in engineering design, logistics, machine learning, robotics, and operations research.
Genetic Algorithm
Simulates biological evolution. Populations of solutions undergo selection, crossover, and mutation across generations — survival of the fittest drives improvement.
Ant Colony Optimisation
Models how ants find shortest paths using pheromone trails. Particularly effective on combinatorial problems like the Travelling Salesman Problem.
Particle Swarm Optimisation
Inspired by bird flocking and fish schooling. Particles explore the search space by balancing personal experience with collective swarm knowledge.
Simulated Annealing
Based on the metallurgical process of annealing. A cooling schedule controls the probability of accepting worse solutions, escaping local optima.
Differential Evolution
A population-based strategy that generates new candidates by arithmetically combining existing ones. Highly competitive on real-valued optimisation.
No Free Lunch Theorem
No single algorithm dominates all problems. Understanding algorithm strengths and problem structure is key to choosing the right approach.
How to use this calculator
Select an algorithm, configure its parameters, and choose a benchmark function. The calculator estimates convergence speed, population diversity, exploitation-exploration balance, and expected solution quality for your configuration — without having to run code. Use it to develop intuition about how parameters affect search behaviour before committing to a full implementation.
