Making Expert Objects
Description
Experts are the "actors" which "bid" to see who conducts the
next test. They contain an object "bidder" that determines bidding strategy
and an object "constructor" that determines which feature it wants to text
next. The runAuction
function calls functions from experts
and gWealth. The makeExpert function is not called directly, but through
makeStepwiseExpert or makeScavengerExpert. Defaults are not set because
these are internal functions called by rai
and
runAuction
and all arguments are required.
