NAME
symphony - mixed-integer linear program (MILP) solver
SYNOPSIS
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]
DESCRIPTION
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.
OPTIONS
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'
