# This script is the command that is executed every run.

|
# Check the examples in examples/

#
|
|
# This script is run in the execution directory (execDir, --exec-dir).

#
|
|
# PARAMETERS:
|
|
# $1 is the candidate configuration number
|
|
# $2 is the instance ID
|
|
# $3 is the seed
|
|
# $4 is the instance name
|
|
# The rest ($* after `shift 4') are parameters to the run
|
|
#
|
|
# RETURN VALUE:
|
|
# This script should print one numerical value: the cost that must be minimized.
|
|
# Exit with 0 if no error, with 1 in case of error
