binsearchtol: binary search with arbitrary resolution

In aaronjfisher/designOptim: Design optimizer

Description

The binsearch function in the gtools package searches only over integers. This is a wrapper for binsearch that also allows searching over the grid of points with distance tol between them. A target must also be entered (see binsearch)

Usage

binsearchtol(fun, tol = 1, range, ...)

Arguments

fun	a function that determines the output over which we search (passed to binsearch)
tol	resolution of the grid over which to search for target (see binsearch)
range	a range over which to search for the input to fun
...	passed to binsearch

Examples

 # best solution here is at x0,
 # which we can find with increasing precision
 x0 <- 10.241
 binsearchtol( function(x) x-x0, target=0, range=c(0,2*x0) , tol=1.00)
 binsearchtol( function(x) x-x0, target=0, range=c(0,2*x0) , tol=0.10)
 binsearchtol( function(x) x-x0, target=0, range=c(0,2*x0) , tol=0.05)
