SYNOPSIS

my $tc = Chess::Plisco::Engine::TimeControl->new(
    searchmoves => ['e2e4', 'd2d4', 'f2f4'],
    ponder => 0,
    movestogo => 40,
    mwime => 5 * 60 * 1000,
    btime => 5 * 60 * 1000,
    winc => 1000,
    binc => 1000,
    depth => 5.
    nodes => 1_000_000,
    mate => 5,
    movetime => 1000,
    infinite => 0,

DESCRIPTION

A Chess::Plisco::Engine::TimeControl processes the parameters for a search and sets the relevant properties of the Chess::Plisco::Engine::Tree.

CONSTRUCTOR

The constructor receives the values parsed as options for the "go" command per the UCI specification.

position

The current position as a Chess::Plisco::Engine::Position object.

start_time

Start time of the current search as an array of seconds and microseconds since the epoch (as returned by "gettimeofday" in Time::HiRes).

allocated_time

The maximum time in ms to think about a move.

nodes_to_tc

When that many nodes have been searched, the time left should be checked again. A negative value means to search infinitely.

move_now

If true, the engine's time is used up and it should move as soon as possible.
