Diagram of the shortest path calculation. An Illustration showing how the shortest path discussed in the report is calculated. It is assumed that; from P1 to P5: p1 = (P1-P6-P7-P5) and l1 = 3. From P1 to P8: p2 = (P1-P6-P7-P8) and l2 = 3. From P1 to P10: p3 = (P1-P9- P10) and l3 = 2. From P1 to P11: p4 = (P1-P11) and l4 = 1.
