Optimization problem class

Description

The OptimizationProblem class is used to represent an optimization problem. Data are stored in memory and accessed using an external pointer. Only experts should interact with this class directly.

Fields

$ptr: externalptr object.
$data: list object.

Usage

x$print()

x$show()

x$repr()

x$ncol()

x$nrow()

x$ncell()

x$modelsense()

x$vtype()

x$obj()

x$pwlobj()

x$A()

x$rhs()

x$sense()

x$lb()

x$ub()

x$number_of_projects()

x$number_of_actions()

x$number_of_features()

x$number_of_branches()

x$row_ids()

x$col_ids()

x$get_data()

Arguments

ptr: externalptr object.

Details
