Compiling the Sequential Version.

• Change to the SYMPHONY-4.0/USER directory and type make. This will first make the SYMPHONY library (sequential version). After making the SYMPHONY library, make will compile the user customization library and link the executable. The name of the executable is specified in the file SYMPHONY-4.0/USER/Makefile and is mip by default. The executable is installed in the directory SYMPHONY-4.0/USER/bin.$(ARCH)/$(LP_SOLVER), where ARCH is the current architecture and LP_SOLVER is the current LP solver, as specified in the makefile. The makefile can be modified to enable parallel execution of the code (see below).

• After the SYMPHONY library is compiled, you are free to type make clean if you want to save disk space. You should only have to remake the library if you change something in SYMPHONY's internal files. To clean the user files, type make clean_user.

• To test SYMPHONY, a sample MPS file called sample.mps is included with the distribution. To specify the file name, use the -F command-line option, i.e., type bin.$(ARCH)/$(LP_SOLVER)/mip -F sample.mps in the SYMPHONY-4.0/USER directory. To obtain more MPS data files for further testing, download the MIPLIB library.

• That's it! Now you are ready to develop your own application by modifying the files in the SYMPHONY-4.0/USER directory and it's subdirectories. See Section 4.2 for more information.
