2025-05-27Removed VLA notation from function parameters.Sebastiano Tronto1-4/+4
I found out that this gives undefined behavior when then size is 0. Better not to have it at all, it is confusing for other developers anyway.
2025-05-19Refactored checkdataSebastiano Tronto1-113/+7
Relevant changes include: - Changed the signature of nissy_checkdata(). - Removed expected_distribution.h from tools; this data is now included in each solver's src/ code. - Removed distribution check for cocsep; may add back later.

2025-04-21Always use unsigned char * for data buffersSebastiano Tronto1-14/+12
Before this commit I was inconsistently using one of void *, char * and uint8_t *.
2025-04-19Improved logging, especially for solveSebastiano Tronto1-42/+36

2025-04-17Small rework of optimal vs maxsolsSebastiano Tronto1-7/+5
I wanted to make the "optimal" and "maxsolutions" options mutually exclusive, but in the end I decided there is value in keeping both (e.g. for specifying a limit to the number of solutions when asking for "all" optimal"). Now optimal cannot be negative anymore, for the same reason of maxsolutions. The interface user (shell, UI) will have to take care of handling this in a way that makes sense for the user. Usually this means setting the maximum number of solutions to UINT_MAX (or a similar very high number) when the user wants "all optimal".
2025-04-15Better logging functionSebastiano Tronto1-11/+10
Now it is possible to provide some data together with the logging function. This is useful for example in C++, where I can now provide an arbitrary callable object as data, and a simple wrapper function that call the callable object as logging function.
2025-04-08Some minor changes to the interface.Sebastiano Tronto1-20/+18
- Simplified logger to accept only a string, not a variadic list of args like printf(). This can still use some improvement, but now it is easier to use from other languages. - Fixed some misuses of the logger (wrong types etc) - Renamed some constants - Fixed some typos in comments.

a few weeks. This include mainly three things: 1. Various tweaks for a total performance gain of around 30%. 2. Take into account symmetries and avoid repeated work. This required a re-work of the splitting into tasks before the solve. 3. Add a second fallback table (eoesep). This gives huge performance gains for particular scrambles (e.g. superflip). After merging this commit, remove and re-generate all pruning tables.

2024-10-10Removed "options" from solver selectionSebastiano Tronto1-66/+46
Now the solver name fully determines the solver (and options) to be used. For example, now one must specify "h48h0k4" as the name of the solver. This PR also fixes a couple of things in tools.
2024-10-06Fix concurrency issuesSebastiano Tronto1-1/+1
So I did not have any misconception about Atomics, I just could not apply it where I did because the logic doesn't allow for it.
2024-10-05Fix rare data raceSebastiano Tronto1-1/+1
I had some misconception about how _Atomic and const worked. This means the previous commit (expected distribution) could be incorrect.
