Exception thrown when using k-G with max degree constraint #8

Open fcole90 opened 6 years ago

Using solver k-G with max degree constraint makes blip crash throwing exceptions.

Try running: java -jar blip.jar scorer.sq -c bdeu -d data/child-5000.dat -j data/child-5000.jkl -n 3 -t 10 and then java -jar blip.jar -j data/child-5000.jkl -r data/child.kg.res -t 10 -w 4 -v 1

When I attempt it I get the following:

Read scores... 
Starting 0 searcher 
... Ended!
