Robusztusoptim is a term that appears to be a portmanteau of the German words "robust" and "optimierung," suggesting a focus on robust optimization. Robust optimization is a field within mathematical optimization that deals with problems where the parameters are uncertain. Instead of assuming precise values for parameters, robust optimization considers them to be within a defined range or set. The goal is to find a solution that is feasible and performs well for all possible realizations of the uncertain parameters within that set.

The core idea behind robust optimization is to achieve a solution that is "robust" against uncertainty, meaning it remains a valid and reasonably good solution even when the actual parameters deviate from their expected values. This contrasts with traditional optimization methods that often rely on exact parameter values, making them sensitive to errors or changes. Robust optimization frameworks typically involve defining an uncertainty set that encompasses all plausible values of the uncertain parameters. The optimization problem is then formulated to minimize the objective function while satisfying constraints for every scenario within this uncertainty set.

This approach is particularly valuable in applications where uncertainty is inherent and the cost of a poor decision is high. Examples include portfolio optimization, where asset returns are uncertain, or supply chain management, where demand or delivery times can fluctuate. By employing robust optimization, decision-makers can gain more reliable and resilient strategies that are less prone to failure due to unforeseen circumstances. The trade-off in robust optimization is often between robustness and optimality; a solution that is extremely robust might sacrifice some performance in the best-case scenario.
