In addition to benchmarks and strategies, we implement the concept of domains and transforms in Summit. Domains specify the decision variables and objectives for a particular optimisation experiment (e.g., all benchmarks include a domain). Transforms enable a domain to be reconfigured to improve the performance of optimisation or enable adaptation of a domain to a particular strategy. For example, we implement transforms for converting multi-objective optimisation problems into single objective optimisation problems. These transforms are used in the S N Ar benchmark.
