Algorithm evaluation reveals improved search efficiency across large-scale optimization tasks, suggesting causal mechanisms enhance evolutionary computation.

Key Points

The study aims to address search efficiency deterioration in large-scale multiobjective optimization problems by integrating causal inference into competitive swarm optimization.
Developed the causal inference-based competitive swarm optimizer (CI-CSO) utilizing information geometric causal inference (IGCI) to map causal links between decision variables and fitness values.
Engineered a causal-information processing module to evaluate positive and negative variable impacts alongside an offspring generator that dynamically alters step size and sampling range based on causal effect variance.
Evaluated performance by embedding the operator into two algorithms (LSTPA and LMOCSO) and benchmarking against six classic algorithms across the LSMOP test suite and five real-world problems with up to 10,000 decision variables.
The causal-information operator successfully distinguished critical variables and their positive or negative impacts on solution quality across high-dimensional search spaces.
CI-CSO demonstrated enhanced search efficiency and competitive performance compared to six classic multiobjective algorithms on test problems featuring up to 10,000 variables.
