Coin-or linear programming solver

 Vol (Volume Algorithm) is a linear programming solver based on the
 subgradient method.
 .
 Vol is part of COIN-OR (COmputational INfrastructure for Operations
 Research) project which is an initiative to spur the development of
 open-source software in operational research - mathematical optimization
 algorithms.
 .
 This package contains the documentation and examples.
