2012-11-01A bunch of fixes to the solver, and moving it in to clang.Zancanaro; Carlo
Also some contribution writing stuff. Basically: lots of work.

2012-10-26Try to make the correct solver into a local solverCarlo Zancanaro
As far as I can tell, it's worked! Hooray!

2012-10-23Make the recursive solver work properly.Carlo Zancanaro
If you ignore the intermediate results for the strategy iteration phase then you're in the clear! I think!
2012-10-22Okay, the solver is now correct.Carlo Zancanaro
It runs in two separate passes: - improve strategy (for all) - evaluate fixpoint Unfortunately this loses out on locality at the moment. I really want a local solver, so I'll have to see what I can do about that.
2012-10-16A quick fix to the solver.Carlo Zancanaro
2012-10-15Fix up to build with clang (and fix another bug)Carlo Zancanaro
- Remove exceptions - Remove dynamic casts The bug was relating to MaxStrategy not cleaning up the influence sets after propagating changes. I just added a call to .clear() and it seems fine.
2012-08-07A whole bunch of clean up work around the place.Carlo Zancanaro
- Make it a bit nicer to use the command-line - Remove the strategies we won't be using - Clean up some code around the place, generally
2012-08-06New variation on the equation system solver.Carlo Zancanaro
Much simpler to understand. Basically have a variable assignment which is dynamic and updates with the strategy changes. Similarly have strategy changes easily invalidate the variable assignment. This makes them strongly inter-dependent, but simplifies the implementation considerably. Proving it should be easier like this, too.
2012-07-09Cleaning up a bit of code around the place.Carlo Zancanaro
- Especially making logging a bit nicer.
2012-07-09Fix a few bugs and add a new example system.Carlo Zancanaro
2012-07-09Better implementation: smarter strategy iterationCarlo Zancanaro
Also add the beginnings of some log stuff, mayhaps.
2012-06-15Parameterise fixpoint and strategy improvementCarlo Zancanaro
(command-line arguments specify which to use) Also: - Fix up Complete<T> to work comparing `inf` to 1 (stupid bug) - Clean up the systems/ folder a bit - Change the printed output to differentiate variables and constants (!v/!c, respectively) - Perform a slight optimisation to the strategy-iteration process
2012-06-15Re-write heaps of code to work better.Carlo Zancanaro
2012-05-28Fix issues with some things ignoring strategies.Carlo Zancanaro
2012-05-28Fix memory error and x = max(-inf, expr) stuff.Carlo Zancanaro
2012-05-17Fix a segfault and a stupid parser decision.Carlo Zancanaro
2012-05-03Add a parser for linear equationsCarlo Zancanaro
(Also add the antlr jar and C runtime)
2012-05-02Fix up some memory leaking issues.Carlo Zancanaro
2012-04-30Functional algorithm. Unoptimised.Carlo Zancanaro
2012-04-26A new attempt. Better strategies implementation.Carlo Zancanaro
Still lacking: - Factories (to set the ids) - Solver - Systems of equations
2012-04-26A bunch of modifications working to a good solver.Carlo Zancanaro
2012-04-20Start on the max-strategy stuff. Also more BF.Carlo Zancanaro
