Parsing Engine Names

In last week's post on engine competitions, TCEC S19 Sufi 75% Finished; CCC15 Still Halted, I wrote,

For the record, the full names of the two [TCEC S19 Sufi] engines are:-
- Stockfish 202009282242_nn-baeb9ef2d183
- LCZero v0.26.3-rc1_T60.SV.JH.92-190
In a future post, I'll try to parse those names.

Under 'Main seasons', Wikipedia TCEC page has a list of all finalists including the full name/version of the engines in the finals.

Top Chess Engine Championship (wikipedia.org)

Stockfish has competed in every TCEC final since S11. The following table shows a naming evolution from DDMMYY to YYMMDD, to adding a version, to YYYYMMDD + version, to NNUE plus some sort of a version probably taken from the contents of the file ('nn-baeb...'):-

S11: Stockfish 260318
S12: Stockfish 180614
S13: Stockfish 18102108
S14: Stockfish 190203
S15: Stockfish 19050918
S16: Stockfish 19092522
S17: Stockfish 20200407
S18: Stockfish 202006170741
S19: Stockfish 202009282242_nn-baeb9ef2d183

Leela has competed in every TCEC final since S14 (except S16). The following table shows an evolution based on incorporating codes into the version:-

S14: LCZero v0.20.2-32930
S15: LCZero v0.21.1-nT40.T8.610
S16: %
S17: LCZero v0.24-sv-t60-3010
S18: LCZero v0.25.1-svjio-t60-3972-mlh
S19: LCZero v0.26.3-rc1_T60.SV.JH.92-190
