While reading around on Cassowary for constraint based UI, I noticed the original author and others expanded their work to a more general linear solver system Balsberg. Maybe something useful to many business, so just thought I'd drop some links... * Solving Interactive Logic Puzzles With Object-Constraints https://www.hpi.uni-potsdam.de/hirschfeld/publications/media/GraberFelgentre... * https://github.com/babelsberg/babelsberg-s * https://homes.cs.washington.edu/~borning/papers/felgentreff-babelsberg-seman... * https://www.hpi.uni-potsdam.de/hirschfeld/publications/media/FelgentreffLehm... btw, what does PolyMath/SciSmalltalk offer in the way of linear solvers? cheers -ben

Hi Ben, so far no linear solvers in PolyMath. i made a small constraint solver for PolyMath that is not restricted to linear problems, hence necessarily slower than linear solvers & not fast enough for UI-layout-problems. a general overview of what that package does is here: https://github.com/SergeStinckwich/SciSmalltalk/wiki/RealInterval-Example-Al... . the constraint solver is described somewhere in the middle of that page. werner
thx for the tip. cheers -ben On Sat, Oct 28, 2017 at 11:47 PM, werner kassens <wkassens@libello.com> wrote:
