twocriterion
Twocriterion is a term used in optimization and decision analysis to denote problems that involve optimizing two objective functions simultaneously. In a twocriterion problem, one seeks solutions that balance competing goals, such as cost and quality, time and reliability, or risk and return. Unlike single-objective optimization, where a single best solution is sought, twocriterion problems typically yield a set of Pareto-optimal solutions, known as the Pareto frontier, in which no objective can be improved without worsening the other.
Common approaches to solving twocriterion problems include scalarization, where the two objectives are combined into a
Applications of twocriterion frameworks span operations research, engineering, economics, and computer science. Examples include production planning
Relation to terminology: twocriterion is closely related to bi-criteria or two-objective optimization. It is a specific
