There are currently other five data files in this directory. They correspond 
to the test problems in Section 4 of J.C. Gonçalves, I. García-Jurado and J.Costa
"Sharing delay costs in stochastic projects."

They are available in files:
10activities, 30activities, 100activities, 300activities and 1000activities.

The format of these data files is:
number of activities,
number of simulations to approximate the TU-game,
matrix of precedences between activities,
sample matrix of the durations vector,
vector of actual durations,
maximum time the project can take without generating delay.
