1 # Known bugs and issues 2 3 I will fix these at some point. 4 5 ## Incomplete filtering when using NISS 6 7 When using NISS, sometimes the switch happens when it does not make sense. 8 For example, for EO: 9 10 ``` 11 nissy solve eoud -a -N -m 5 -M 5 -p "R' U' F R D L' B' L2 U2 R' B U2 B2 R2 B2 D' F2 U D2 R2 D B2 R U R' U' F" 12 ``` 13 14 The last 4 EOs returned by this command start with `D2 U (switch...)`: 15 16 ``` 17 ... 18 D2 U (L F D) 19 D2 U (L F D') 20 D2 U' (L F D) 21 D2 U' (L F D') 22 ``` 23 24 These EOs should not be included, because the starting `D2` move is useless. 25 26 It is possible that this issue affects other steps too. 27 28 ## Optimal solver duplicate solutions 29 30 There is an issue with move ordering that leads to the same solution occasionally being listed 31 twice. 32 33 To reproduce: 34 35 ``` 36 nissy solve optimal -o "R' F' D2 L' U' L B D L2 F2 L' U2 R' F2 R' D2 F2 U2 F'" 37 ``` 38 39 Output: 40 41 ``` 42 U' D2 F B' U R' U D B R' B' U' L D2 F2 B2 L (17) 43 U' D2 F B' U R' U D B R' B' U' L D2 B2 F2 L (17) 44 ``` 45 46 The two solutions are the same, but with `F2 B2` swapped.
