Map 1 in 54 | Comment 4 of 9 |

Dej Mar:

I see you've just posted more solutions for Maps 2-4, which I haven't checked through yet, but I think there's a problem with your Map 1 solution which, based on your questions, may/may not affect your other maps.

My spin on the rules is that you can't 'traverse' (as in go down/along the same road) twice, but you can certainly cross an earlier route at an intersection or two 'L-turns can meet as described.  But the problem also states a 'location' (A to G) can't be revisited, so it would seem these 7 intersections can only be used for their one in-sequence visit by the courier, and not otherwise used in any way by earlier or subsequent moves.

Your fourth move from 5f by three units over to 2f takes you right back through the A at 4f, which you've already visited in your first move.  Also, I think you've missed a 1 unit move from 7d to 6d before your 3 move down to 6g.

I think the following better's Charlie's initial start by six moves (ie. 54):

*4  0   0

4f   6   6

5f   1   7

5e  1   8

2e  3  11

2g  2  13

3g  1  14

3c  4  18

2c  1  19

2d  1  20

7d  5  25

7c  1  26

6c  1  27

6g  4  31

9g  3  34

9c  4  38

8c  1  39

8i   6  45

9i   1  46

9h  1  47

4h  5  52

4*  2  54
