Solutions

class Solutions(capacity: Int = defaultCapacity, var allowInfeasibleSolutions: Boolean = false) : SolutionsIfc(source)

Class to support a group of solutions (all containing inputs, responses, objective fns, penalties) The solutions are naturally ordered by comparison of Solution instances based on their penalized objective functions (without regard to sampling error).

Parameters

capacity

the capacity for the solutions. Constrains the total number of solutions in-memory. The default capacity is defaultCapacity. Oldest solutions are evicted first.

allowInfeasibleSolutions

if true input-infeasible solutions are allowed to be saved. If false, input-infeasible solutions are silently ignored. The default is false (do not allow input-infeasible solutions to be saved)

Constructors

Solutions

constructor(solutions: List<Solution>, capacity: Int = defaultCapacity, allowInfeasibleSolutions: Boolean = false)

constructor(capacity: Int = defaultCapacity, allowInfeasibleSolutions: Boolean = false)

Properties

allowInfeasibleSolutions

var allowInfeasibleSolutions: Boolean

capacity

open override var capacity: Int

The capacity of the sequence of solutions.

enteredSolutions

val enteredSolutions: List<Solution>

A time-ordered list of the solution, where 0 is the first (oldest) solution added, 1 is the next, etc.

orderedInputFeasibleSolutions

open override val orderedInputFeasibleSolutions: List<Solution>

A list of solutions that are input feasible ordered by penalized objective function.

orderedSolutions

open override val orderedSolutions: List<Solution>

A list of solutions ordered by penalized objective function. The solutions may or may not be feasible.

size

open override val size: Int

Functions

add

open override fun add(solution: Solution): Solution?

Adds the solution to the solutions.

addAll

open override fun addAll(solutions: List<Solution>): List<Solution>

Adds all the solutions to the sequence of solutions. If the capacity is met, then the oldest (first) item is evicted and returned. Each evicted item is returned in the order of eviction.

clear

open override fun clear()

Clears all solutions
