Hi Amr

I was looking for a solution for this problem for a while, how to solve the Chinese postman problem also known as the Route inspection problem if the number of nodes is greater than 25??? I know it could be solved using bit-masks technique by pairing the nodes with odd degree and adding the minimum pairing cost, but can this problem be solved in a faster way??? if yes, can you please give me some links to read about???

Thanks in advance :D
