1. Problem description
Wide-receiver's trace is on the sline curve which is composed with
the starting point and 4 other ones assigned by users. This slpine curve
has a parameter which is the distance measured from the starting point.
This parameter provides dividing the route into almost equal short portion
of line. It can be also applied to proceed the diffences' position. The
short portion of line of diffences is 10% longer than that of the receiver.
It means that he run 10% slower than them. The right side edge of the section
paper is the goal.
The puesuiting algorithm of diffences is simple, which is so-called
homing. Do you reme
