PSO for the HP Prime's Solver??
While preparing for my talk at HHC2015, I was studying Generic Algorithms (GA) using Excel VBA and Matlab before I port the VBA code to the HP Prime. I also took a look at Particle Swarm Optimization (PSO) and found a lot of Matlab code in books, in Mathwork's File Exchange web pages, and the Internet at large. I decided to write Excel VBA code for PSO to get a better feel for things. I was blown away how PSO has outmatchod the GA method. PSO's success comes at requiring fewer parameters AND giving accurate results (not approximate ones usually given by the GA methods).
I think the HP Prime can benefit from an implementation of the PSO algorithm for its Solver, especially when it comes to solving the roots of 3,4, or even more nonlinear equations. The only change that comes with using the PSO algorithm is the need to specify ranges for the roots of each variable. While this is a small extra cost, you have the ability to significantly guide Solver to look for the roots you want! Tim, I hope you are reading this!! Namir
