From: H.G.Muller Date: Sun, 2 Dec 2018 10:40:18 +0000 (+0100) Subject: Implement option ' ponder always' X-Git-Tag: v4.0~26 X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=8e699739bef4730a34efb65939800a3a3b6f13b0;p=uci2wb.git Implement option ' ponder always' UCI2WB can now also be configured to let the UCI engine ponder even in force mode. This is useful during OTB tournaments, when the GUI is still in book (and thus keeps the engine in force mode). Because there is no ponder move at this stage, the engine will be set pondering on the opponent's position, and the ponder move is set to an empty string to force a ponder miss afterwards. --- diff --git a/UCI2WB.c b/UCI2WB.c index 9d568f7..178cdcb 100644 --- a/UCI2WB.c +++ b/UCI2WB.c @@ -48,7 +48,7 @@ int statDepth, statScore, statNodes, statTime, currNr, size, collect, nr, sm, in char currMove[20], moveMap[500][10], /* for analyze mode */ canPonder[20], threadOpt[20], varList[8000], anaOpt[20], backLog[10000], checkOptions[8192] = "Ponder"; char pvs[99][999], board[100]; // XQ board for UCCI char *nameWord = "name ", *valueWord = "value ", *wTime = "w", *bTime = "b", *wInc = "winc", *bInc = "binc", newGame; // keywords that differ in UCCI -int unit = 1, drawOffer, scores[99], mpvSP, maxDepth; +int unit = 1, drawOffer, scores[99], mpvSP, maxDepth, ponderAlways; volatile int logLen, sentLen; FILE *toE, *fromE, *fromF; @@ -185,7 +185,7 @@ LoadPos(int moveNr) } void -StartPonder() +StartPonder(int moveNr) { if(!move[moveNr][0]) return; // no ponder move LoadPos(moveNr+1); @@ -206,7 +206,7 @@ Release() if(len <= 0) return 0; StopPonder(pondering | searching); pondering = searching = 0; // force new search if settings change during analysis (multi-PV!) fwrite(backLog + sentLen, 1, len, toE); sentLen += len; DPRINT("# release %d\n", len); - if(ponder && computer == 1 - stm) StartPonder(); // (re)start ponder search + if(ponder && computer == 1 - stm) StartPonder(moveNr); // (re)start ponder search return analyse; // return 1 if analysis search should be restarted } @@ -287,7 +287,7 @@ Engine2GUI() sscanf(p+7, "%s", move[moveNr]); if(computer != NONE && ponder) { DPRINT("# ponder on %s\n", move[moveNr]); - StartPonder(); + StartPonder(moveNr); } p[-1] = '\n'; *p = 0; // strip off ponder move } else move[moveNr][0] = 0; @@ -455,7 +455,7 @@ GUI2Engine() } EPRINT((f, "\n")) searching = 1; // suppresses spurious commands during analysis starting new searches } else pause = think = 2, StartSearch(""); // request suspending of input processing while thinking - } + } else if(ponderAlways && computer == NONE) move[moveNr][0] = 0, StartPonder(moveNr-1); nomove: for(difficult=0; !difficult; ) { // read and handle commands that can (or must) be handled during thinking fflush(toE); fflush(stdout); @@ -485,6 +485,7 @@ GUI2Engine() char *p; if(logLen == sentLen) logLen = 0, sentLen = 0; // engine is up to date; reset buffer if(sscanf(line+7, "UCI2WB debug output=%d", &debug) == 1) ; else + if(sscanf(line+7, "ponder always=%d", &ponderAlways) == 1) ; else if(sscanf(line+7, "Floating Byoyomi=%d", &flob) == 1) ; else if(sscanf(line+7, "Byoyomi=%d", &byo) == 1) ; else if(p = strchr(line, '=')) { @@ -519,7 +520,7 @@ GUI2Engine() continue; } if(!strcmp(command, "resume")) { - if(suspended == 2) StartPonder(); // restart interrupted ponder search + if(suspended == 2) StartPonder(moveNr); // restart interrupted ponder search suspended = think = 0; continue; // causes thinking to start in normal way if on move or analyzing } if(think) { // command arrived during thinking; order abort for 'instant commands' @@ -550,6 +551,7 @@ GUI2Engine() if(!varList[0]) strcpy(varList, sc=='s' ?
