Abstract

We study how many bits of objective-function information population-based metaheuristics require. A decision-level interface separates the true objective from the fitness visible to the optimizer. Differential Evolution (DE), Particle Swarm Optimization (PSO), and a real-coded Genetic Algorithm (GA) are evaluated on five functions in 3,600 paired runs. Under dynamic comparison-relative quantization, Minimum Sufficient Fitness Resolution (MSFR) ranges from 1 to 6 bits, but one bit is worse than full precision for every algorithm-function pair. Fixed-reference controls perform substantially worse, showing that bit depth and range allocation cannot be separated. Low-resolution outcomes also depend on tie policy.
