eArtius Optimization Plug-In For Simulia Isight

eArtius - Isight 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 - Isight 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 are based on 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 - Isight plug-in is simple to insert into your existing Isight Environment. Simple install the plug-in, drag it into the design gateway to replace the existing optimization component and now optimize your model with eArtius' advanced optimization technology. The MGE algorithm will generate optimal solutions, the MGP algorithm will allow you to take a solution that was generated by MGE and drive along the Pareto frontier to further improve higher priority objectives. HMGE and HMGP hybrid algorithms allow finding global Pareto frontier and covering it evenly 2-20 times faster compared with best commercial genetic algorithms.

With eArtius - Isight plug-in designers have many more Pareto optimal trade-off designs to chose from in the design cycle time, thereby creating more innovative products. eArtius – Isight plug-in is truly of strategic value to any organization, allowing engineers to produce more trade-off designs to chose from when you have many competing design objectives.
