@Rajadodve786 @Epix101, thanks for your replies.
For the shape, I would like to use Raja suggestion, and the picture is creative.
For the position, I have my encryption and probably I will stick with my original plan.
In a MP, do:
- Locate the biggest country (BC) on a map, name peg 0
- From BC, Start from clockwise search the surrounding countries, name peg x:1, 2, 3, …, 9
- The outer loop countries, find two biggest surrounding countries from x, and name the country with 10x+y e.g. 21, 41 means the same name Chile, and thus we know 12 Argentina and 14 Chile means the biggest two surrounding coutry and easier to locate Chile.
- If the map is too big, i.e. Asian: Divide the map into smaller pieces, such as 4 sectors: China group, Indonesia Iran and Saudi Arabia. Then do steps 1-3.
2 Argentina 21 Chile
4 Bolivia 41 Chile
5 Peru 51 Ecuador
6 Colombia 61 Ecuador
10 French Guiana
