eArtius Optimization Plug-in for Noesis OPTIMUS

eArtius - OPTIMUS plug-in provides four innovative multi-objective optimization algorithms. The algorithms utilize eArtius' new fast approach of gradient estimation (DDRSM), and new multi-objective optimization techniques such as directed optimization on Pareto frontier and hybrid genetic algorithms + gradient techniques. Synergy of these techniques allows highly dimensioned multi-objective problems to be solved in a fraction of the time that other methods require.

eArtius - OPTIMUS plug-in includes four multi-objective optimization algorithms:

  • Multi-Gradient Explorer (MGE) algorithm uses a conventional approach for optimization practice. It starts from an initial point, and iterates toward Pareto frontier until a Pareto optimal point is found. Then it takes another initial point, iterates again, and so on;
  • Multi-Gradient Pathfinder (MGP) algorithm uses Pareto frontier as a search space for multi-objective optimization, and performs in this way directed optimization on Pareto frontier. Directed optimization on Pareto frontier means that a search algorithm steps along Pareto frontier from a given initial Pareto optimal point towards a desired Pareto optimal point;
  • Hybrid Multi-Gradient Explorer (HMGE) combines a GA framework with unique eArtius approach to estimate gradients. In this way HMGE combines strengths and avoids weaknesses of two major optimization approaches: gradient-based techniques and Genetic Algorithms (GAs);
  • Hybrid Multi-Gradient Pathfinder (HMGP) algorithm is a new multi-objective optimization algorithm which combines elements of MGP (Multi-Gradient Pathfinder) algorithm with elements of genetic algorithms (GA).

All eArtius optimization algorithms use a new approach of gradient estimation developed at eArtius: Dynamically Dimensioned Response Surface Method (DDRSM). DDRSM is equally efficient for low-dimensional and high-dimensional tasks. It requires just 5-7 model evaluations to estimate gradients regardless of task dimension. DDRSM has been tested with up to 5,000 design variables.

eArtius - OPTIMUS plug-in is simple to insert into your existing OPTIMUS Environment. After the deployment has been performed, all four multi-objective optimization algorithms become accessible from the OPTIMUS graphical user interface (see the above screenshots.)
