numpy.random.PCG64.advance¶
method

random.PCG64.
advance
(delta)¶ Advance the underlying RNG asif delta draws have occurred.
 Parameters
 deltainteger, positive
Number of draws to advance the RNG. Must be less than the size state variable in the underlying RNG.
 Returns
 selfPCG64
RNG advanced delta steps
Notes
Advancing a RNG updates the underlying RNG state asif a given number of calls to the underlying RNG have been made. In general there is not a onetoone relationship between the number output random values from a particular distribution and the number of draws from the core RNG. This occurs for two reasons:
The random values are simulated using a rejectionbased method and so, on average, more than one value from the underlying RNG is required to generate an single draw.
The number of bits required to generate a simulated value differs from the number of bits generated by the underlying RNG. For example, two 16bit integer values can be simulated from a single draw of a 32bit RNG.
Advancing the RNG state resets any precomputed random numbers. This is required to ensure exact reproducibility.
