#
# Load the initial population from a file or not
# To use the default setting type "default"
#
# Usage: Load population (0|1)
#
# For example, if you want random initialization type 0
# On the other and if you want to load the initial population from a
# file, type
# 	1 <population file name> [0|1]
#
# Valid options for "Load population" are 0/1
# If you type "1" you must specify the name of the file to load the
# population from. The second optional parameter which indicates 
# whether to evaluate the individuals of the loaded population or not.
0

# Save the evaluated individuals to a file 
#
# To use default setting type "default".
#
# Here by default all evaluated individuals are stored and you will be
# asked for a file name later when you run the executable.
# 
# Usage: Save population (0|1)
# For example, if you don't want to save the evaluated solutions type 0
# On the other and if you want to save the evaluated solutions
# 	1 <save file name>
#
# Note that the evaluated solutions will be appended to the file.
#
# Valid options for "Save population" are 0/1
# If you type "1" you must specify the name of the file to save the
# population to.
