org.pokersource.enum.BeliefVector
public abstract class BeliefVector
extends java.lang.Object
Represents subjective beliefs about the possible hands held by a
player. Maintains a mapping from each hand to its probability of
occurrence.
BeliefVector(String spec) - Instantiate self from string respresentation.
|
(package private) void | addHandGroupAbsolute(HandGroup group, double absoluteProb) - During construction, add a new hand group with its absolute probability
of occurrence.
|
(package private) void | addHandGroupRelative(HandGroup group, double relativeProb) - During construction, add a new hand group with its probability of
occurrence relative to the Bayesian probability.
|
(package private) void | addRemainingAbsolute(double absoluteProb) - During construction, add each hand not yet added with the given absolute
probability of occurrence of the entire set of such hands.
|
(package private) void | addRemainingRelative(double relativeProb) - During construction, add each hand not yet added with its probability of
occurrence relative to its Bayesian probability.
|
abstract void | fromString(String spec) - Instantiate self from string respresentation.
|
double | getBeliefProb(long hand) - Return the absolute probability that hand will occur, conditioned on
the dead cards.
|
long[] | getHands() - Return an array of bitmasks representing hands with nonzero probability
of occurring (conditioned on the dead cards).
|
int | numHands() - Returns the number of atomic hands with nonzero probability of occurring
(conditioned on the dead cards).
|
void | setDeadCards(long cards) - Set the "dead cards", cards that are known not to be available.
|
String | toString() - Generate string representation of self; the inverse of fromString().
|
String | toStringAtomic() - Generate a string representation of self that gives probability
details for all atomic hands, conditioned on the dead cards.
|
(package private) void | validate() - After construction, subclasses should call this for a sanity check.
|
universalGroup
(package private) HandGroup universalGroup
The universe of all possible hands. Should be set in the subclass'
constructor. Used by addRemaining() to know which hands haven't
yet been added.
BeliefVector
public BeliefVector(String spec)
Instantiate self from string respresentation. Meant to be called from
subclass's constructor. The subclass constructor should then parse the
string spec and populate groupProb and deadCards.
addHandGroupAbsolute
(package private) void addHandGroupAbsolute(HandGroup group,
double absoluteProb)
During construction, add a new hand group with its absolute probability
of occurrence. The sum of absolute probabilities over groups should be
1. Meant to be called by subclass's fromString().
addHandGroupRelative
(package private) void addHandGroupRelative(HandGroup group,
double relativeProb)
During construction, add a new hand group with its probability of
occurrence relative to the Bayesian probability. Meant to be called by
subclass's fromString()
addRemainingAbsolute
(package private) void addRemainingAbsolute(double absoluteProb)
During construction, add each hand not yet added with the given absolute
probability of occurrence of the entire set of such hands. The sum of
absolute probabilities over groups should be 1. Meant to be called by
subclass's fromString().
addRemainingRelative
(package private) void addRemainingRelative(double relativeProb)
During construction, add each hand not yet added with its probability of
occurrence relative to its Bayesian probability. Meant to be called by
subclass's fromString()
fromString
public abstract void fromString(String spec)
Instantiate self from string respresentation. This method must be
implemented by all subclasses. Also, subclass constructors should call
super(spec) and then fromString(spec).
getBeliefProb
public double getBeliefProb(long hand)
Return the absolute probability that hand will occur, conditioned on
the dead cards.
getHands
public long[] getHands()
Return an array of bitmasks representing hands with nonzero probability
of occurring (conditioned on the dead cards).
numHands
public int numHands()
Returns the number of atomic hands with nonzero probability of occurring
(conditioned on the dead cards).
setDeadCards
public void setDeadCards(long cards)
Set the "dead cards", cards that are known not to be available. This
sets the probability to zero of any hand including any of these cards
increases the probabilities of the other hands in proportion.
toString
public String toString()
Generate string representation of self; the inverse of fromString().
toStringAtomic
public String toStringAtomic()
Generate a string representation of self that gives probability
details for all atomic hands, conditioned on the dead cards.
validate
(package private) void validate()
After construction, subclasses should call this for a sanity check.
