calibrate_step

Stepwise VES inversion using different optimization algorithms

calibrate_step(ves, opt.method, max.layers = 10, lower = c(1, 1),
  upper = c(500, 100), trace = FALSE)

Arguments

ves

A VES object
opt.method

A character string specifying the optimization method to be used
max.layers

An integer with the maximum number of layers to be testsed
lower

A numeric vector with min values of the real resistivity and thickness
upper

A numeric value with max values of the real resistivit and thickness
trace

A logical flag indicating if optimization information must be shown

Value

This function returns a list with the following entries:

  • par: A numeric vector with the values of the layer resistivities and thicknesses

  • value: The value or the RSS (Residual sum of squares)

  • rel.error: The value of the relative error (in percentage)

  • cal.error: A matrix with the RSS and relative error at each iteration
