MontecarloEvaluator class

An iterable object that evaluates pot equity for each player in the given situation. It iterates with evaluating situations by montecarlo simulation.

By default it iterates infinitely (MontecarloEvaluator.length is always -1) so use something (e.g. .take(10000)) to limit iteration.

final evaluator = MontecarloEvaluator(
  communityCards: ImmutableCardSet.parse("3c6dTs"),
  players = [
    HandRange.parse("As3h"),
    HandRange.parse("8d8h"),
    HandRange.parse("AQs-ATsAKo-AJo44+"),
  ],
);

let wons = [0, 0, 0];

for (final matchup in evaluator.take(100000)) {
  for (final i in matchup.wonPlayerIndexes) {
    wons[i] += 1;
  }
}

print(wons);  // => [15928, 44819, 40103]

Methods

any(bool test(Matchup element)) → bool
Checks whether any element of this iterable satisfies test.
inherited
cast<R>() → Iterable<R>
A view of this iterable as an iterable of R instances.
inherited
contains(Object? element) → bool
Whether the collection contains an element equal to element.
inherited
elementAt(int index) → Matchup
Returns the indexth element.
inherited
every(bool test(Matchup element)) → bool
Checks whether every element of this iterable satisfies test.
inherited
expand<T>(Iterable<T> toElements(Matchup element)) → Iterable<T>
Expands each element of this Iterable into zero or more elements.
inherited
firstWhere(bool test(Matchup element), {Matchup orElse()?}) → Matchup
The first element that satisfies the given predicate test.
inherited
fold<T>(T initialValue, T combine(T previousValue, Matchup element)) → T
Reduces a collection to a single value by iteratively combining each element of the collection with an existing value
inherited
followedBy(Iterable<Matchup> other) → Iterable<Matchup>
Creates the lazy concatenation of this iterable and other.
inherited
forEach(void action(Matchup element)) → void
Invokes action on each element of this iterable in iteration order.
inherited
join([String separator = ""]) → String
Converts each element to a String and concatenates the strings.
inherited
lastWhere(bool test(Matchup element), {Matchup orElse()?}) → Matchup
The last element that satisfies the given predicate test.
inherited
map<T>(T toElement(Matchup e)) → Iterable<T>

inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
reduce(Matchup combine(Matchup value, Matchup element)) → Matchup
Reduces a collection to a single value by iteratively combining elements of the collection using the provided function.
inherited
singleWhere(bool test(Matchup element), {Matchup orElse()?}) → Matchup
The single element that satisfies test.
inherited
skip(int count) → Iterable<Matchup>
