Especially for a hackathon we generated synthetic data the closest to reality which described a bond graph with between different subscribers. Tops of the graph there were more than one million.

Later, we in a special way rustled these data, having destroyed some of communications. The task was — to recover the maximum number of communications in passing, without having created a set of new edges, early not existing.

We were not limited to the simple fact of existence of any communication between users, but also added information on value and a form of communication between them.

Description of fields of the file:

A — Id of an abonet And,
B — Id of an abonet of B,
x_A — Id of the operator of an abonet And,
x_B — Id of the operator of an abonet In,
c_AB — quantity of calls from And to In,
d_AB — duration of calls from And to In,
c_BA — quantity of calls from In to And,
d_BA — duration of calls from In to And,
s_AB — quantity of SMS from And to In,
