Plot the runs of a multiple start blvim

Source: R/blvim_logs.R
autoplot.blvim_logs.Rd

Displays the runs of blvim() described by sim_logs().

Usage

# S3 method for class 'blvim_logs'
autoplot(object, type = c("staircase", "scatter"), ...)

Arguments

object

a data frame of class blvim_logs produced by sim_logs()

type

the type of graphical representation, "staircase" or "scatter"

...

additional parameters (not used currently)

Value

a ggplot object

Details

With type = "staircase" (default), the final potentials of the runs are shown by decreasing value as a function of their rank. Each plateau corresponds to a final configuration, and its width to the number of runs that reach it.

With type = "scatter", the final potential of each run is shown as a function of its number of evaluations (for the gradient algorithms) or iterations (for the other algorithms).

In both cases, the colour gives the status of the run (see sim_logs()).
