set.params: Set ls.problem instance parameters.

Description

Updates the chosen parameters of an object of class ls.problem.

Usage

set.params(lsp, lsTimeLimit = lsp$params$lsTimeLimit, lsIterationLimit = lsp$params$lsIterationLimit, lsTimeBetweenDisplays = lsp$params$lsTimeBetweenDisplays, lsSeed = lsp$params$lsSeed, lsNbThreads = lsp$params$lsNbThreads, lsAnnealingLevel = lsp$params$lsAnnealingLevel, lsVerbosity = lsp$params$lsVerbosity, indexFromZero = lsp$params$indexFromZero)

Arguments

lsp

problem instance created with ls.problem.

lsTimeLimit

the number of the seconds which will be spent to optimize the objective function (functions), or a vector of times (in seconds) assigned to each objective function. The length of the vector should correspond to the length of the number of objective functions.

lsIterationLimit

the number of iterations made to optimize the objective function (functions), or a vector of iteration numbers assigned to each objective function. The length of the vector should correspond to the length of the number of objective functions.

lsTimeBetweenDisplays

the time (in seconds) between successive displays of the information about the search (default: 1)

lsSeed

pseudo-random number generator seed (default: 0).

lsNbThreads

the number of threads over which the search is paralleled (default: 2).

lsAnnealingLevel

simulated annealing level (no annealing: 0, default: 1).

lsVerbosity

verbosity (no display: 0, default: 1).

indexFromZero

indicates whether the data and decision variables (vectors and matrices) are to be indexed from 0. If FALSE (by default), they will be indexed from 1.

Value

updated ls.problem instance.

Examples

model.text.lsp <- lsp.model.example('extdata/knapsack.txt')
lsp <- ls.problem(model.text.lsp)
lsp <- set.params(lsp, lsTimeLimit=10, lsIterationLimit= 5)
