| 2021-12-23 | Fixes for yesterday's commit | Sebastiano Tronto | 4 | -12/+31 | |
| 2021-12-23 | Added the possibility to compress tables to 2 bits per entry. | Sebastiano Tronto | 3 | -33/+108 | |
| This is done similarly to nxopt: one base value is selected and entries are memorized based on that base value. Values higher than base+3 are returned as base+3 (still a valid estimate) and values lower or equal to base require a lookup on a "fallback" table, which must give a valid estimate for the larger one (e.g. nxopt31 or khuge can fallback to drud_sym16). I have also added some info to the pruning table files: base value and distribution. Unfortunately this means that everyone who has used nissy 2.0beta has to re-generate the tables. | |||||

| 2021-12-16 | Added a new pruning table (equivalent to nxopt31). I have not tested it yet, ↵ | Sebastiano Tronto | 14 | -323/+547 | |
| it takes a while to generate. Plus I have done a whole lot of refactoring in random places because I cannot focus on one thing at the time. | |||||

| 2021-12-13 | Faster optimal solver. | Sebastiano Tronto | 8 | -287/+616 | |
| This is a pretty big one, but unfortunately performance only improved by about 5%. I implemented one of the main ideas of nxopt, that is switching to the inverse scramble on the fly if it gives a lower branching factor. On the one hand it makes sense that it does not have such a huge impact, since it only rarely happens that we do have a lower branching factor on inverse, but on the other hand I am quite sad that the improvement is barely noticeable :-( Maybe the problem is that I have introduced a lot of new overhead and I can improve that in the future. Or maybe I am just overlooking something stupid. | |||||

| 2021-11-15 | Fixed used of uninitialized aux variable | Sebastiano Tronto | 1 | -1/+5 | |
| 2021-11-13 | Fixed a problem with htr-drud coordinates. The corresponding pruning table ↵ | Sebastiano Tronto | 4 | -19/+43 | |

| 2021-11-12 | I tried to remove the dependence on antindex in order to get rid of them | Sebastiano Tronto | 4 | -24/+151 | |
| once and for all. I successfully removed from the pruning table generation part by using an alternative (slower) method, but then I realized that I also use antindexes when generating symmetry data. So I reverted to the original pruning table computation method, but I left the alternative way there, commented. | |||||

| 2021-11-12 | Fixed anti-index for eofbepos. It did not compute a value for eorl, which | Sebastiano Tronto | 1 | -1/+28 | |
| causes problems when using this coordinate combined with symmetries (e.g. in symcoord khuge, drud and similar). This actually reverts a change that I made before the first commit of v2. | |||||
