Each character in path is the direction from the last waypoint:

In parentheses are given by recurrence. The number after the closing parenthesis indicates the number of repetitions. For example 75 (85)9 3 (14)9 1 is translated into 75 858585858585858585 3 141414141414141414 1.

For symmetric open tours:

a) If the last character of the path is an asterisk, the path is repeated again in reverse order. For example 74774761383* is translated into 74774761383 38316747747.

b) If the last character of the path it is '>', the path is repeated again in reverse order without the last character. For example 1661661835225> is translated into 166166183522 5 225381661661.
