Description

Title Runs run_simulation in parallel over parameters Provides a wrapper to perform a line search of a parameter and returns the results of run_simmulation with the parameters specified.

Usage

1
run_parallel(params, varied_parameter, from, to, by, ...)

Arguments

params

Parameters for 'run_simulation'

varied_parameter
from

Starting value of varied parameter, See 'seq'.

to

Final value of varied parameter. See 'seq'.

by

Increment value. See 'seq'.

mc_opts

Options for mclapply, setting mc.cores is a good idea.

Value

A list of the result of calling run_simulation with the varied parameter.
