|Random Optimization is useful in two cases:
1. It is difficult to find a suitable starting design for the refinement procedure. In such cases it may be useful to carry out a sequence of optimization procedures with random starting designs. Because of highly efficient optimization algorithms used in OptiLayer, this design approach often provides good results. This procedure is typically used for solving complicated design problems when good starting designs are unknown.
2. It is required to generate a set of different designs for finding a design with better manufacturability.
|OptiLayer generates a sequence of starting designs with the indicated number of layers and average layer thickness. Each design is optimized by one of the chosen numerical methods. The process continues until you interrupt it. The best results are being stored in the Collection storage (see left panel). These results can be used later as starting designs for the needle optimization procedure or for the gradual evolution. They can be easily extracted from the Collection storage and loaded into memory.
It is also possible to use Design mode where the search area of the Random Optimization is specified as some vicinity of the loaded design. It is possible to set constraints for each layer thickness, usually it significantly improves computational performance and quality of obtained solutions. Specified layer thickness limits are taken into account both when starting designs are specified and when local optimization procedures are performed.
