The Desert Sparrow Optimization (DSO) algorithm is a nature-inspired metaheuristic optimization technique that mimics the foraging behavior of sparrows in desert environments. It leverages the strategies employed by sparrows to survive and thrive in harsh, resource-constrained habitats. The algorithm is characterized by its simplicity, efficiency, and effectiveness in solving complex optimization problems across various domains. This research aims to better understand desert sparrows by Analysing their cooperative work allocation behaviour and developing an algorithm to Minimise Makespan.
