The units i ∈ [1,n] need to reach a goal area
from a start area without colliding with the
environment and with each other, while at
the same time they must stay together as a
coherent group. The goal is reached when all
units are within the goal area.

Compute a backbone path for a single unit
The corridor is defined around the backbone
Units will move along the backbone using
attraction points
The distance between attraction points for
the different units is limited, guaranteeing
coherance.

We used Microsoft Visual Studio.Net 2002 with the C++ programming language.
All experiments were run on a Pentium IV 2.4 Ghz computer with
1 Gb RAM running Microsoft Windows XP.
