This is for the read me file for program 1S,2S,3S, and 4S: we use input information file to distinguish between them. 

I test it under microsoft visual c++ 6.0

to run the program:
>TSP <infofile name>

The format of infofile is as follows:

<the number of patient's locations>
<location 1>
<location 2>
...
<location p>
<the number of nurse's locations>
<location 1>
<location 2>
...
<location p>
<the maximum number of patients one nurse can serve>

Note that location must has the following format: x,y

for program 1s, I have typed the location infomation into file tspinfo.txt
to test program 1s, run:
>TSP tspinfo.txt

for program 3s, I have typed the location infomation into file tsp_info_full.txt
to test program 3s, run:
>TSP tsp_info_full.txt

to test 2s or 4s, change the infomation file accordingly.

Note that the result is shown on screen.
