The resulting catalog lies in the file cat/new_cd.txt and its format in the file cat/new_format.txtSteps to reproduce: The main algorithm generates an instance of a problem called 2-Matching (a generalization of the Matching Problem). Then, it decomposes that instance into several components that are solved separately. Each component is solved via integer programming by using the state-of-the-art solver GuRoBi. A diagram is provided to show the different steps of the cross-identification process (see diagram.png). This piece of software requires GuRoBi 6.5.2 and the WCSTools 3.8.7 library, which can be donwloaded from: 1) http://www.gurobi.com 2) ftp://cfa-ftp.harvard.edu/pub/gsc/WCSTools/wcstools-3.8.7.tar.gz Before compiling, insert the content of wcstools-3.8.7\libwcs into the folder libwcs. Then, do the following: 1) Add the following line to the file wcscon.c (after the line #include "wcs.h"): #define strncasecmp(x,y,z) _strnicmp(x,y,z) 2) Comment the line 375 of the file wcslib.h.
