get_instanceID_seed_pairs: Returns the pairs of instance IDs and seeds used as instances...

In irace: Iterated Racing for Automatic Algorithm Configuration

Returns the pairs of instance IDs and seeds used as instances in the race (and optionally the actual instances).

Description

Returns the pairs of instance IDs and seeds used as instances in the race (and optionally the actual instances).

Usage

get_instanceID_seed_pairs(iraceResults, index, instances = FALSE)

Arguments

iraceResults	list()|character(1) Object created by irace and typically saved in the log file irace.Rdata. If a character string is given, then it is interpreted as the path to the log file from which the iraceResults object will be loaded.
index	integer() Indexes of the (instanceID,seed) pairs to be returned. The default returns everything.
instances	logical(1) Whether to add the actual instances as an additional column (only if the instances are of atomic type).

Value

data.table()
With default arguments, a data.table containing two columns "instanceID" and "seed". With instances=TRUE and if the instances are of atomic type (see is.atomic()) type, another column instance is added that contains the actual instance.

Examples

log_file <- system.file("exdata/irace-acotsp.Rdata", package="irace", mustWork=TRUE)
head(get_instanceID_seed_pairs(log_file))
# Add the instance names
get_instanceID_seed_pairs(log_file, index=1:10, instances=TRUE)
