概要	Robust Ant Colony Optimization (Robust ACO) extends the classic ant colony metaheuristic by explicitly incorporating parameter uncertainty and worst-case or expected-case robustness criteria into the solution search. Rather than optimizing for a single nominal scenario, it seeks solutions that perform well across a range of plausible problem realizations, making it suitable for real-world combinatorial problems where input data (costs, demands, travel times) are uncertain or variable.	Robust Simulated Annealing (RSA) adapts the classical simulated annealing metaheuristic to seek solutions that perform well not just under nominal conditions but across the full range of uncertain or adversarial parameter values. By embedding a robustness evaluation — worst-case, expected-case, or regret-based — into the SA acceptance step, RSA trades some nominal optimality for resilience, making it valuable when problem parameters are imprecisely known or subject to environmental variation.
