Agreed… still you could get rid of the for loops:

(1 to vol-1 map (maxSeq(_))).foldLeft(0){_+_}

I purposely did not look into the fold operators yet since the few mentions I’ve seen in the Scala blogosphere seems to suggest it doesn’t help readability.. and by looking at your implementation I tend to agree It does get max points for expressive power though!

That for loops makes my eyes bleed

What about using a range, a map and the fold operator?

def baseVal(vol: Int): Int = (0 /: (0 to vol-1 map(maxSeq(_))))(_+_);
