TimeSpaceConstr.ActionSequences

Description

This module defines an interface for constructing action sequence expressions, required for the TimeSpaceConstr.TimeSpaceConstraints module, in order to construct time space constraints.

Synopsis

Documentation

actionSeqConstraint Source #

Arguments

:: Int

The number of actions

-> String

The name of the action sequence variable

-> ASExpr

The action sequence expression

-> ModelData 

The main method of this module for constructing action sequence constraints. Takes the action sequence expression and produces a HaskellZinc expression.

atleast_cells Source #

Arguments

:: Int

The minimum amount of cells in the sequence

-> ASExpr 

Restrict the model to at least contain a given amount of locations.

atmost_cells Source #

Arguments

:: Int

The maximum amount of cells in the sequence

-> ASExpr 

Restrict the model to at most contain a given amount of locations.

atleast Source #

Arguments

:: Int

The action in question

-> Int

The min number of times this action has to be performed

-> ASExpr 

Require the given action to be executed at least a given amount of times, in each location.

atmost Source #

Arguments

:: Int

The action in question

-> Int

The max number of times this action can be performed

-> ASExpr 

Require the given action to be executed at most a given amount of times, in each location.

incompatible Source #

Arguments

:: Int

The first of the incompatible actions

-> Int

The second of the incompatible actions

-> ASExpr 

Require that the two given actions are never executed together in any location.

implication Source #

Arguments

:: Int

The action that implies the second action

-> Int

The action that is implied

-> ASExpr 

Require that if the first action is executed, the second has to be executed as well in the same location.

value_precedence Source #

Arguments

:: Int

The action that has to precede the second action

-> Int

The action that has to be preceded by the first action

-> ASExpr 

Require the given action action to always precede the second given action.

stretch_min Source #

Arguments

:: Int

The action in question

-> Int

The min number of times the action has to be performed in a row once it has been performed at least once

-> ASExpr 

Require the if the given action is executed, it has to at least be executed a given number of times in a row.

stretch_max Source #

Arguments

:: Int

The action in question

-> Int

The max number of times the action may be performed in a row

-> ASExpr 

Require the if the given action is executed, it can at most be executed a given number of times in a row.

or_as Source #

Arguments

:: Int

The first of the two actions, at least one of which has to be performed

-> Int

The second of the two actions, at least one of which has to be performed

-> ASExpr 

Require each location to execute at least one of the two given actions.

data ASCostExpr Source #

An action sequence cost expression

actionSeqCost Source #

Arguments

:: String

The name of the action sequence variable

-> String

The name of the variable containing the resulting cost

-> ASCostExpr

The cost expression

-> ModelData 

The main method of this module for constructing cost constraints. Takes the cost expression and produces a HaskellZinc expression.

uniformCost Source #

Arguments

:: Int

The action for which the cost is given

-> Int

The uniform cost for this action

-> ASCostExpr 

Constraint the cost of the given action to uniformly be the given number.

discountCost Source #

Arguments

:: Int

The action for which the cost is given

-> Int

The action which moves to the next station

-> Int

The initial cost

-> Int

The discounted cost

-> Bool

The local flag

-> ASCostExpr 

Constraint the cost of the given action to initially be the given full cost, and afterwards be the given discounted cost.

dependentCost Source #

Arguments

:: Int

The action for which the cost is given

-> Int

The action which influences the cost

-> Int

The action which moves to the next station

-> Int

The original cost

-> Int

The discounted cost

-> Bool

The local flag

-> ASCostExpr 

Constraint the cost of the given action to be the given full cost, if the influencing is not executed, or the given discounted cost otherwise.

data ASCostPredExpr Source #

An action sequence cost predicate expression

actionSeqCostPreds Source #

Arguments

:: [ASCostPredExpr]

The list of cost predicate expressions

-> [ModelData] 

The main method for constructing cost predicates. Takes a list of cost predicate expressions and produces a list of HaskellZinc predicates.
