Double objective optimization
Web21 gen 2024 · In the decision variable optimization, the grouped decision variables are optimized with an adaptive scalarization strategy, which is able to adaptively balance the convergence and diversity of the solutions in the objective space. The proposed algorithm is evaluated with a suite of test problems with 2–10 objectives and 200–1000 variables. A multi-objective optimization problem is an optimization problem that involves multiple objective functions. In mathematical terms, a multi-objective optimization problem can be formulated as $${\displaystyle \min _{x\in X}(f_{1}(x),f_{2}(x),\ldots ,f_{k}(x))}$$ where the integer $${\displaystyle k\geq 2}$$ is … Visualizza altro Multi-objective optimization or Pareto optimization (also known as multi-objective programming, vector optimization, multicriteria optimization, or multiattribute optimization) is an area of multiple-criteria decision making that … Visualizza altro When a decision maker does not explicitly articulate any preference information the multi-objective optimization method can be classified as no-preference method.
