Detailed Description

A discrete distribution over non-negative integer set [n] for some n over a given probability distribution.

Note that this class does not satisfy RandomNumberDistribution requirement due to missing many required interfaces.

Constructor & Destructor Documentation

Walker() [1/4]

taco::Walker::Walker ( )

inline

Default constructs walker in an invalid state.

Walker() [2/4]

taco::Walker::Walker

(

const std::vector< double > &

prob

)

Constructs a discrete distribution over the integer set [0, prob.size()- 1] with the specified distribution.

prob needs to be normalized. Otherwise it is undefined.

Walker() [3/4]

taco::Walker::Walker ( const Walker &  )

default

Walker() [4/4]

taco::Walker::Walker ( Walker &&  other )

inline
