Directions for using the two executable Fortran programs.

Open up a Command Line Prompt. (Do a help search on MS_DOS if you need to learn how to do this with a windows system.)

Move the Command Line Prompt to the location of the data and executable files (i.e., EXAMPLE.DAT, HESSIAN.EXE, and OPT2LD.EXE) that is to the directory in which you placed these files on your computer. Use the change directory line command; i.e., CD in order to make these moves.

From the Command Line Prompt type in the program that you wish to run; either OPT2LD.EXE OR HESSIAN.EXE. (Note that OPT2LD.EXE must be run in order to have its output available as input to HESSIAN.EXE.)

Input the data as requested (SEE COMMENTS BELOW).

Output can be written to a file for subsequent access by other programs; e.g., WordPad.


What follows is a listing of the data file EXAMPLE.DAT with appended comments.

4		The number of partitions	
3		The number of TPs in the first partition
0.2		Proportion of all turns in the first partition
0 6		Coordinate pair of first TP in first partition
4 8		Coordinate pair of the second TP
1 8		Coordinate pair of the third TP
4		The number of TPs in the second partition
0.3		etcetera

5 4		Coordinates of the fourth TP in the fourth partition

Note that the program will automatically close the traverse on the first TP for each of the partitions.

The program will now request information that is to be entered from the keyboard. 

The number of facility locations to be optimized: 2

Initial location for each landing [Enter each (x,y) pair one at a
time skipping a space between the x and y coordinates.] E.G., after
the first prompt: 1 3 and after the second: 5 6.

Enter the C0, C1 and C2 cost coefficients for each polygon when prompted; after the first prompt: 5.6 3.046 0.0. Note that these
coefficients are the same for all 4 partitions in this example.

Request printed output.

Enter a file name for the output. E.G., FIRST.OUT

Exit the program.

Open the executable file HESSIAN.EXE

Enter the data file name: EXAMPLE.DAT

Input the Delta Increment to be made about the critical point. E.G., 0.001

Now refer to the output from OPT2LD.EXE found in FIRST.OUT

Input (x,y) for the first landing critical point: 1.2626 5.2406 and
do the same for the second landing when prompted: 5.4038 4.2688.

Enter the cost coefficients for each partition as before:
5.6 3.046 0.0. etc.

The results are only shown on the screen.

"exit" the DOS command line.
