Re: cable laying problem
- I find your problem specification somewhat confusing. I would be
helped by a sample arrray of about 5 x 5 together with a text
describing what the array represents.
It might also be useful to know what resolution is desired. Some
methods that might be useful for a 100 x 100 array might not work well
due to space or time considerations on a 10,000 x 10,000 array.
Hope I can help.
