get_instanceID_seed_pairs function

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

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).

Returns

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)
