- I was playing around with my computer and tried to program
- a self avoiding random walk in 2 dimensions.
- The 'particle' can move in any direction (k*pi/2) except to
- those places which it has already before occupied.
- The steplength is constant 1 unit.
- After some time this particle is trapped because it can't
- turn in any direction anymore:
-
- for example ______
- | _ |
- start |__|
-
- It seems to be that the average length of a path is
- about 116 units.
- I was wondering if there is any proof of this or if
- this a yet unsolved problem and if there is some good
- literature about this.
