Constructors

WeightedState(Int32, Weight)

Declaration
public WeightedState(int index, Weight weight)
Parameters
Type Name Description
Int32 index
Weight weight

Properties

Index

Index of the state.

Declaration
public readonly int Index { get; }
Property Value
Type Description
Int32

Weight

Declaration
public readonly Weight Weight { get; }
Property Value
Type Description
Weight

WeightHighBits

High bits of the state weight. Only these bits are used when comparing weighted states for equality or when calculating hash code.

Declaration
public readonly int WeightHighBits { get; }
Property Value
Type Description
Int32
Remarks

Using high bits for hash code allows to have "fuzzy" matching of WeightedStateSets. Sometimes there's more than one way to get to the same weighted state set in automaton, but due to using floating point numbers calculated weights are slightly off. Using only high 32 bits for comparison means that 20 bits of mantissa are used. Which means that difference between weights (in log space) is no more than ~~ 10e-6 which is a sufficiently good precision for all practical purposes.
