[closed] looking for an algorithm to walk on new paths

I am looking for an algorithm.

I want to start at a certain point in a map, then follow a path on my gps-device, which starts and ends at the same point while always having a distance of about distance. I want to - if possible - always go on new streets. Finally I should have a set of tracks that have every street covered around a starting point while trying to not walk the same street twice.

Idea:

1. I get a vector map and start at point Start programmatically.
2. Then I loop through north, east, south, west and in between with 1° resolution, ie 360°.
3. In this loop I walk to the first crossing, turn right, to the next, turn right and then aim at Start, finding the closest way to Start using this method.

Here I want inspiration...
