WebCompilers perform transformations, not optimization. Optimization at compile time, even if based on realistic performance models, would be wildly expensive (NPNP) True optimization would have to involve evaluating or accurately modeling performance. Actual performance is often data dependent. Best transformations are often domain dependent. 21
WebI have been designing microfluidics for non-Newtonian fluids using the numerical method of topology optimization. This involved dividing the world into small elements and finding out whether each element should have material in it or not, in order to have optimal performance. I later went to London to optimize said optimization method using a …
WebApr 28, 2024 · Topology optimization has drawn increasing attention as a method to aid the design of engineering systems. Gradient-based optimization is typically used to solve these problems because of its efficiency in dealing with a large number of design variables.
