Important: the subject must start with [QHV]
We are currently distributing the source code for linux 32 bits. The code is optimized to a core2 processor with SSE2. To compile use make in the source directory.
The new generator that produces randomly and uniformly distributed points on a hyper-sphere surface is available. To compile the generator use:
QHV accepts files in WFG format, a text file with point per line and coordinates separated by spaces. A Set of points begins with a line that starts by #. These lines are otherwise ignored and can be used for comments. File dots.wfg exemplifies the format for a 3D space.
To compute the hyper-volume for this file use:
Use the binary with the appropriate number of dimensions. If the first argument is not provided the it runs in interactive mode. Hence we can also use:
The resulting output should be:
Doxygen documentation is available for:
The uniform point generator receives the number of dimensions through the first argument, the number of points throw the second, and the number of test sets throw the third. one. The following commands generates 2 sets of 10 points uniformly distributed on the surface of a 13D hyper-sphere.
To use the gnuplot scripts put the script in the same dir as the file dots.wfg and issue the following commands:
Use the proper script, in this case 3D. The sed command is used to increase point thickness in xfig, so that fig2dev exports properly. Other formats are available.
To use the script with another.wfg file link it, or rename it, as dots.wfg.
Quick HyperVolume is an algorithm that computes the HyperVolume occupied by a set of hyper-rectangles, that share the "lower leftmost" vertex.
Extensions of the algorithm to compute Exclusive HyperVolumes and use several cores are described in The Journal of Heuristics.
