Format of the file describing each instance:
============================================

First line:

number_of_operations, number_of_precedence_relations, number_of_machines

Subsequent number_of_precedence_relations lines:

Pairs of the form i1 i2 meaning that operation i2 cannot start being
processed before the completion time of operation i1.

Subsequent number_of_operations lines:

Each line i starts with the number of machines that can process
operation i and, in the sequel, contains pairs of the form k pik,
denoting that operation i can be processed in machine k with
processing time pik. (The machines are numbered from 0 to
number_of_machines - 1).

Subsequent number_of_machines lines:

Each line k contains the values \gamma^proc_k, \gamma^on_k,
\gamma^off_k, \gamma^idle_k, \tau^on_k, \tau^off_k.

The last line contains the value of \gamma^extra.
