Detailed Description

Runs a grid search sampler.

Member Function Documentation

/brief Runs the grid search sampler.

Parameters

_L	An object of class likelihood.
range_min	Vector of doubles holding the minimun value for each parameter.
range_max	Vector of doubles holding the maximun value for each parameter.
num_samples	Vector of integers holding the number of divisions for each parameter.
output_file	A string holding the name of the output file. The output has a column for each parameter and the last column is the chi squared value associated to the parameters in that row.
output_precision	Sets the output precision – the number of significant digits used to represent a number in the sampler output files. The defaul precision is 6.

Here is the call graph for this function:

Parameters

num_batches	Integer value. Number of regions of parameter space handled by different cpu groups.
num_likelihood	Integer value. Number of cpus allocated to each region of parameter space. These processes evaluate every single likelihood in parallel.
