# Class "CDEPD"

### Description

Class for the definition of the Deterministic Equivalent Problem

### Objects from the Class

Objects can be created by calls of the form `new("CDEPD", ...)`

, or
more conveniently by the generator function `DEP()`

.

### Slots

`MP`

:`"CLPD"`

: The master or first-stage LP.`q`

:`"matrix"`

: The objective(s) in the second-stage (per row for each scenario).`W`

:`"matrix"`

: The recourse-matrix.`h`

:`"matrix"`

: The absolute values of the rhs-constraints (per row for each scenario).`Tech`

:`"list"`

: The technology matrices combined in a`list`

object.`SubDir`

:`"character"`

: The relational operators to be used in the second stage.`prob`

:`"vector"`

: The probability for each scenario.`K`

:`"integer"`

: The count of scenarios.

### Methods

- addTheta
Including the value function in the objective of the master problem.

- checkAddFeasCut
Tests and adds a feasability cut to the master-problem.

- checkAddOptCut
Tests and adds an optimality cut to the master-problem.

- createRhsSubLP
Evaluates rhs-constraints of sub-problems.

- createSubLP
Creates list of sub-problems for a given

*\mathbf{x}*.- getA
