GMCM(1)

This was the first day of the first national graduate mathematical contest of modeling(GMCM, shorted by myself). GMCM was little different with UMCM(MCM for Undergraduate). There were four problems of GMCM, But only two for UMCM. The first one was related to positioning system. Lots of related knowledge and sub-problems need to be solved. The second one was the minimum cost of materials problem. The third one was about data mining problem. There were lots of information about the after-sale services of automobiles. The last one was about bi-selection between supervisors and graduates.

After our discussion we chose the first one. It was hard. As it had nine sub-problems. And we spent nearly one whole day to solve the first one. Fortunately, we had got some perfect solution. We were excited. But we had little sleep in the night.

Let us try our best to solve the problems left.
