Optimization budget specification object — ldmppr

Objects of class ldmppr_budgets define optimizer budget/options used by estimate_process_parameters.

Usage

# S3 method for class 'ldmppr_budgets'
print(x, ...)

# S3 method for class 'ldmppr_budgets'
summary(object, ...)

# S3 method for class 'summary.ldmppr_budgets'
print(x, ...)

# S3 method for class 'ldmppr_budgets'
as.data.frame(x, ...)

# S3 method for class 'ldmppr_budgets'
length(x)

# S3 method for class 'ldmppr_budgets'
x[i, ...]

# S3 method for class 'ldmppr_budgets'
as.list(x, ...)

Arguments

x: an object of class ldmppr_budgets.
...: unused.
object: an object of class ldmppr_budgets.
i: indices of local stages to keep: 1 = first level, 2 = refinement levels.

Value

print(): prints a brief description of configured budgets.
summary(): returns a summary.ldmppr_budgets.
as.data.frame(): a compact table of the global/local budget entries (when present).
length(): number of available local budget stages (1 or 2).
[ ]: subset local budget stages (keeps global options).
as.list(): returns the underlying list structure.

Details

A ldmppr_budgets is a list with (at minimum):

global_options: list of NLopt options for the global stage (e.g., maxeval, maxtime).
local_budget_first_level: list of NLopt options for the local stage at the first/coarsest grid level.
local_budget_refinement_levels: optional list of NLopt options for local refinement levels (used only when estimate_process_parameters(strategy = "multires_global_local")).

Functions

print(ldmppr_budgets): Print a brief summary of optimization budgets.
summary(ldmppr_budgets): Summarize an optimization budget specification.
print(summary.ldmppr_budgets): Print a summary produced by summary.ldmppr_budgets().
as.data.frame(ldmppr_budgets): Convert budgets to a data.frame.
length(ldmppr_budgets): Number of available local budget stages.
[: Subset local budget stages (keeps global options).
as.list(ldmppr_budgets): Extract the underlying list representation.
