uci_go: Sending command go for chess engine

In bigchess: Read, Write, Manipulate, Explore Chess PGN Files and R API to UCI Chess Engines

Description

Sending command go for chess engine. Info about go command from http://wbec-ridderkerk.nl/html/UCIProtocol.html start calculating on the current position set up with the "position" command. There are a number of commands that can follow this command, all will be sent in the same string. If one command is not send its value should be interpreted as it would not influence the search.

Usage

uci_go(
  engine,
  depth = NULL,
  infinite = FALSE,
  stoptime = 1,
  wtime = NULL,
  btime = NULL,
  winc = NULL,
  binc = NULL
)

Arguments

engine	engine object
depth	integer depth (search x plies only)
infinite	boolean default FALSE. If TRUE, stoptime (next argument) should be defined
stoptime	integer default 1. Used in Sys.sleep after go infinite in egine. After this, uci_stop() is executed
wtime	integer default NULL (white has x msec left on the clock)
btime	integer default NULL (black has x msec left on the clock)
winc	integer default NULL (white increment per move in mseconds if x > 0)
binc	integer default NULL (black increment per move in mseconds if x > 0)

Value

engine object

Examples

# Linux (make sure you have executable permission):
engine_path <- "./stockfish_10_x64"
# Windows
# engine_path <- "./stockfish_10_x64.exe"
e <- uci_engine(engine_path)
e <- uci_go(e,depth = 10)
uci_quit(e)
# Using pipe '%>%' from magrittr:
require(magrittr)
uci_engine(engine_path) %>% uci_go(depth = 10) %>% uci_quit()
# Find best answer for black after 1. e4 in 100 seconds:
uci_engine(engine_path) %>% uci_position(moves = "e2e4") %>%
  uci_go(depth = 20) %>% uci_quit() %>% uci_parse()
# Find best answer for black after 1. e4 in 100 seconds:
uci_engine(engine_path) %>% uci_position(moves = "e2e4") %>%
  uci_go(infinite = TRUE,stoptime = 100) %>% uci_quit() %>% uci_parse()
