SF11 vs 12 Test
Per cercare di capire meglio le potenzialità del nuovo motore credo che non ci sia nulla di meglio di un "test a testa" col suo predecessore su qualche posizione bella tosta.

Ecco la prima che vi propongo:

Il Bianco muove e vince.

Utilizzare esclusivamente le versioni ufficiali di SF11 e SF12; qui non ci interessa tanto sapere quanto siano veloci gli altri, ma solo vedere come se la cava la nuova corazzata ... biggrin.gifbiggrin.gif

Molto interessanti queste posizioni.

Ho provato la prima posizione col mio notebook (un i7 4 core/8 thread di qualche anno fa)

Ho fatto due test. Il primo senza MultiPV, il secondo con MultiPV 8 (1 per thread)

Nel primo caso, SF 12 trova la mossa vincente in circa 11 minuti e 4 miliardi di nodi, contro SF11 che la trova in 7:55 e circa 4 miliardi di nodi anch'esso:

2GB assegnati a ciascun motore.

Con il multiPV attivato SF12 trova la mossa vincente in circa 9 secondi intorno a depth 24 ma la alterna con Kb5b4 è solo dopo depth 30 (sul mio PC dopo 49 secondi) che propende decisamente g7g8B:

SF11 fa meglio, impiega 4 secondi e depth 23, e depth 28-29 per non mollarla più (circa 30 secondi):

Dato che più o meno il numero dei nodi per trovare le posizioni è lo stesso, credo che in questo caso la rete NNUE (e quindi l'algoritmo di valutazione) non influenzi il risultato (valutazione simile o uguale all'algoritmo classico), ma la maggiore complessità computazionale ne determina un tempo di risoluzione maggiore.

Grazie per aver riportato i tempi di soluzione, Geralt.

Effettivamente in alcune posizioni altrimenti molto complesse, l'uso dell'analisi Multi PV consente di velocizzare enormemente i tempi di soluzione.

Per gli scopi del nostro test, il confronto andrebbe fatto senza multi pv, così da verificare l'incidenza degli algoritmi di taglio del motore.

Ecco invece la quarta posizione:

Ho fatto una analisi anche della seconda posizione, stavolta senza multi pv attivato.

SF12 trova la mossa vincente dopo 11 secondi circa a depth 37.
