for measure type = "quality" we always impute with 10 * max_val.
a) it is bad that the user cannot change this behavior / magic constant. what happens here should be exposed. or at least documented and the user told to imputed himself.
b) it does not work at all if we maximize. bug
Tests are currently excluded via .Rbuildignore. Including them causes errors because of the path to the test data sets under inst/.
Replace with smaller dataset(s) and make sure that they run without warnings.
probably some brackets are mismatched
The instance names are sorted a certain way in the ASLIB-files. Depending on locale the sorting order on other computers can be different. The scenario-names as contained in algo.runstatus get resorted, whereas those in algo.runs do not get resorted. Therefore these two orderings can become inconsistent. Note that I have not encountered a bug as a direct result form this inconsistency, I simply thought it was worth pointing out.
Proposed fix: resort algo.runs as well.
Note: all other datastructures in an aslib scenario containing instance-names should also be checked for consistency
Reproduceable example
library(aslib)
scenarioFolderLocation = "C:...\aslib_data-aslib-v2.0"
scenarioName = "SAT11-HAND"
scenario = parseASScenario(paste(scenarioFolderLocation, scenarioName, sep=""))
print(scenario$algo.runstatus$instance_id[1]) #[1] "./SAT02/handmade/chu-min-li/urquhart/urquhart3_25bis.shuffled.cnf"
print(scenario$algo.runs$instance_id[1]) #"./SAT11/crafted/kullmann/VanDerWaerden/VanderWaerden_pd_3k/VanDerWaerden_pd_2-3-21_399.cnf"

Hi,
I was trying to do algorithm selection for machine learning data. When building a model the R interpreter makes an error. I pasted my commands as well as the output:
feurerm@aadpool4:~/Software/R-3.2.1/bin$ ./R

The R interpreter is freshly compiled and runs under Ubuntu 14.04. I tried the ASP benchmark from the ASLIB and it worked without problems.
