Test case generator for Travelling Salesperson 2D problem on Kattis (oldkattis:tsp).
Simply type make on a system with a recent version of GCC.
The program will output the number of points followed by an "x y" pair for each generated point.
Usage: mkgraph [ -h | -hn | -hu ] [ [ -n <spec> | -u <spec> ] ... ]
-h Print general help.
-hn Print help for the -n option.
-hu Print help for the -u option.
-n <spec> Generate normally distributed cluster of points.
Use -hn for information about format of <spec>.
-u <spec> Generate uniformly distributed cluster of points.
Use -hu for information about format of <spec>.
The -n and -u options may be repeated to create several clusters.
If no options are given, the default is -n 1000,0,0,200000,200000.
Usage: mkgraph -n npoints,mean_x,mean_y,dev_x,dev_y
Generates a normally distributed cluster of points where
npoints is the number of points in the cluster,
mean_x is the mean x value,
mean_y is the mean y value,
dev_x is the standard deviation in the x direction,
dev_y is the standard deviation in the y direction.
The option may be repeated to create several clusters
Usage: mkgraph -u npoints,x,y,width,height
Generates a uniformly distributed cluster of points where
npoints is the number of points in the cluster,
x,y is the top left position of the area to contain the points,
width is the width of the area to contain the points,
height is the height of the area to contain the points.
The option may be repeated to create several clusters
As a small example, lets generate 20 points normally distributed around (5, 5) with standard deviation 1 in both directions, and 10 points uniformly distributed over a 10 x 10 area starting at (0, 0):
$ ./mkgraph -n 20,5,5,1,1 -u 10,0,0,10,10
