* Quick fix for bugSebastiano Tronto2025-05-251-9/+8
|
* Do all loggin in main threadSebastiano Tronto2025-05-237-92/+124
| | | | | | | | | | | | | | | | | Before this committ, the solver (via the generic solution-appender routines in src/solve/solutions.h) and the H48 data generator did some logging in the worker threads, without using any locks. This was not nice, but in practice it did not cause any problem, because the log messages were rare. However, this turned out to be a problem when building to WASM, because web workers do not have access to the main JS memory, and therefore they cannot call functions from the main JS. This includes not only the callback functions for logging, but also those for polling the status of the solver (run / pause / stop). This commit fixes this at the cost or being somewhat inelegant: the solutions are not logged as they are found, but only every 500ms.
* Refactored checkdataSebastiano Tronto2025-05-1917-225/+401
| | | | | | | | 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.

* Improve order of moves in NISS solutionsSebastiano Tronto2025-04-201-18/+62
| | | | | | | | Now the side that has more moves is written first. For example: write (U L F) B instead of B (U L F) This also fixes the test on appendsolutions, which used an older version of the function's signature.
* Improved logging, especially for solveSebastiano Tronto2025-04-1912-125/+114

|
* Small rework of optimal vs maxsolsSebastiano Tronto2025-04-176-40/+31
| | | | | | | | | | | | | | 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".
* Log solutions as they are foundSebastiano Tronto2025-04-153-7/+18
|
* Better logging functionSebastiano Tronto2025-04-153-17/+22
| | | | | | | 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.

* | Some minor changes to the interface.Sebastiano Tronto2025-04-088-43/+59
|/ | | | | | | | | - 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.
