Reading the 'BestParameterSet.txt' output file

Description

This function reads the contents of the the ‘BestParameterSet.txt’ output file, which stores the best parameter set and its corresponding goodness-of-fit value found during the optimisation

Usage

read_best(file="BestParameterSet.txt", verbose=TRUE)

Arguments

file	character, name (including path) of the output file with the best parameter set and its corresponding best fitness value found during the optimisation

Examples

## Not run: 
# Setting the user home directory as working directory
setwd("~")

# Number of dimensions to be optimised
D <- 4

# Boundaries of the search space (Sphere test function)
lower <- rep(-100, D)
upper <- rep(100, D)

# Setting the seed
set.seed(100)

# Runing PSO with the 'Sphere' test function, writting the results to text files
hydroPSO(fn=sphere, lower=lower, upper=upper,
        control=list(maxit=100, write2disk=TRUE, plot=TRUE)  ) 
  
# Reading the best parameter set and its corresponsing gof found by hydroPSO
