Detailed Description

Represents a symbolic probability with a numerator and denominator.

The SymProb struct is designed to handle symbolic probabilities using symbolic expressions.

Constructor & Destructor Documentation

SymProb() [1/2]

gymbo::SymProb::SymProb ( )

inline

Default constructor for SymProb.

Initializes the numerator and denominator with constant symbolic expressions representing 1.0.

SymProb() [2/2]

gymbo::SymProb::SymProb ( Sym *  numerator, Sym *  denominator  )

inline

Parameterized constructor for SymProb.

Parameters

numerator	Pointer to the symbolic expression representing the numerator.
denominator	Pointer to the symbolic expression representing the denominator.

Member Function Documentation

eval()

float gymbo::SymProb::eval ( std::unordered_map< int, float > &  params, float  eps, std::unordered_map< int, DiscreteDist > &  var2dist, std::vector< std::vector< int >> &  D  )

inline

Evaluates the SymProb for given parameters, epsilon, variable assignments, and distributions.

Parameters

params	Map of variable index to parameter values.
eps	Epsilon value for numerical stability.
var2dist	Map of variable index to DiscreteDist.
D	Vector of variable assignments.

Returns

The evaluated probability as a float.

marginalize()

std::pair<Sym *, Sym *> gymbo::SymProb::marginalize ( std::unordered_map< int, DiscreteDist > &  var2dist, std::vector< std::vector< int >> &  D  )

inline

Marginalizes the SymProb over given variable assignments.

Parameters

var2dist	Map of variable index to DiscreteDist.
D	Vector of variable assignments.

Returns

Pair of Sym pointers representing the marginalized numerator and denominator.

operator*()

SymProb gymbo::SymProb::operator* ( SymProb  other )

inline

Multiplies two SymProb instances.

Parameters

other

The SymProb to multiply with.

Returns

Result of the multiplication operation as a new SymProb instance.

pmul()

SymProb* gymbo::SymProb::pmul ( SymProb *  other )

inline

Multiplies two SymProb instances.

Parameters

other

The SymProb to multiply with.

Returns

Result of the multiplication operation as a new SymProb instance.

query()

Sym gymbo::SymProb::query ( SymType  symtype, Sym &  other, std::unordered_map< int, DiscreteDist > &  var2dist, std::vector< std::vector< int >> &  D  )

inline

Queries the SymProb with a given symbolic type, another symbolic expression, and variable assignments.

Parameters

symtype	Symbolic type for the resulting Sym.
other	Another symbolic expression.
var2dist	Map of variable index to DiscreteDist.
D	Vector of variable assignments.

Returns

Resulting Sym based on the query.

toString()

std::string gymbo::SymProb::toString ( )

inline

Converts SymProb to a string.

Returns

A string representation of the SymProb.
