In the example, and in the first problem of the testsuite, perhaps it should read r=3; c=3 (instead of r=3; c=4)? Also some of the testsuite problems seem to have multiple solutions (non-unique shortest-path solution)...
Yes.. totally screwed up in test 1, 4 and 7. Will fix within today.. thanks
Fixed the test suite and example in the statement. Looks clean now :)
