"close" is defined by the * * option explained below. this basic type of annotation works by first * * using the normal tree search algorithm to find the best move. if this * * move was the move played, no output is produced. if a different move is * * considered best, then the actual move played is searched to the same depth * * and if the best move and actual move scores are within of each * * other, no comment is produced, otherwise crafty inserts the evaluation for * * the move played, followed by the eval and PV for the best continuation it * * found. you can enter suggested moves for Crafty to analyze at any point * * by simply entering a move as an analysis-type comment using (move) or * * {move}. Crafty will search that move in addition to the move actually * * played and the move it thinks is best. * * * * the format of the command is as follows: * * * * annotate filename b|w|bw|name moves margin time [n] * * * * filename is the input file where Crafty will obtain the moves to annotate, * * and output will be written to file "filename.can". * * * * annotateh filename b|w|bw|name moves margin time [n] * * * * can be used to produce an HTML-compatible file that includes bitmapped * * diagrams of the positions where Crafty provides analysis. this file can be * * opened by a browser to provide much easier 'reading'. * * * * where b/w/bw indicates whether to annotate only the white side (w), the * * black side (b) or both (bw). you can also specify a name (or part of a * * name, just be sure it is unique in the name tags for clarity in who you * * mean). * * * * moves indicates the move or moves to annotate. it can be a single move, * * which indicates the starting move number to annotate, or it can be a range, * * which indicates a range of move (1-999 gets the whole game.) * * * * margin is the difference between Crafty's evaluation for the move actually * * played and for the move Crafty thinks is best, before crafty will generate * * a comment in the annotation file. 1.0 is a pawn, and will only generate * * comments if the move played is 1.000 (1 pawn) worse than the best move * * found by doing a complete search. * * * * time is time per move to search, in seconds. * * * * [n] is optional and tells Crafty to produce the PV/score for the "n" best * * moves. Crafty stops when the best move reaches the move played in the game * * or after displaying n moves, whichever comes first. if you use -n, then it * * will display n moves regardless of where the game move ranks. * * * ******************************************************************************** */ #define MIN_DECISIVE_ADV 150 #define MIN_MODERATE_ADV 70 #define MIN_SLIGHT_ADV 30 void Annotate() { FILE *annotate_in, *annotate_out; char text[128], tbuffer[512], colors[32]={""}, pname[128]={""}; int annotate_margin, annotate_score[100], player_score, best_moves, annotate_wtm; int annotate_search_time_limit, search_player; int twtm, path_len, analysis_printed=0; int wtm, move_num, line1, line2, move, suggested, i; int searches_done, read_status; PATH temp[100], player_pv; int temp_search_depth; TREE * const tree=local[0]; char html_br[5]={""}; int save_swindle_mode, save_asymmetry; int html_mode=0; /* ---------------------------------------------------------- | | | first, quiz the user for the options needed to | | successfully annotate a game. | | | ---------------------------------------------------------- */ save_swindle_mode=swindle_mode; save_asymmetry=king_safety_asymmetry; if (!strcmp(args[0],"annotateh")) { html_mode = 1; strcpy(html_br,"
