Data about helicopters
Description
A small database with real helicopter names and criteria that make sense. The values and weights are generated at random. The only requirement for the methods is that their sum be 1. The set of Cost - Benefit flags make no sense in terms of the criteria they refer to and are just a set of strings starting with the letter "C" (cost) or "B" (benefit). That is, a criterion that must be monotonic of benefit want to maximize it) can have a "c" flag, while a criterion that the (we user would rightly judge to be cost (we want to minimize it) can have a "b" flag.
