symphony - mixed-integer linear program (MILP) solver
symphony [ -hagrtbd ] [ -u ub ] [ -p procs ] [ -n rule ] [ -v level ] [ -s cands ] [ -c rule ] [ -k rule ] [ -m max ] [ -l pools ] [ -i iters ] [ -f parameter_file_name ] [-j 0/1] [-o tree_out_file]
This manual page briefly documents the symphony command. symphony is a generic MILP solver that can be invoked from the command line (through an interactive shell or in a batch mode), or by linking to the provided callable library. When no options are given symphony enters the interactive shell mode. Otherwise the program enters the batch mode, for which a summary of options is included below.
At a minimum, one must specify the name of the file to be read and solved. -h help -a no cut timeout -d enable graph drawing -g use cut generator -r do repricing in root -t trim the tree -b don't perform branch and cut -u ub use upper bound 'ub' -p procs allow 'procs' active nodes -n i use node selection rule 'i' -v i set verbosity to level 'i' -s cands use 'cands' candidates for strong branching -k i use rule 'i' to select child -m n allow a max of 'n' cuts to enter per iteration -e n allow a max of 'n' cut pools -l n k load balance level 'n' and iterations 'k' -i n allow a max of 'n' iterations in presolve -f file read parameters from parameter file 'file' -j 0/1 whether or not to generate cgl cuts -z n set diving threshold to 'n' -o file output vbc-like tree information to file 'file' Solver-specific switches: symphony [ -H ] [ -FL file ] -H help (solver-specific switches) -F model model should be read in from file 'model' (MPS format is assumed unless -D is also present) -L model LP format model should be read in from file 'model' -D data model is in AMPL format and data is in file 'data'
