abstract = "We consider simultaneous evolutionary synthesis of
multiple functions, and verify whether such approach
leads to computational savings compared to conventional
synthesis of functions one-by-one. We also extend the
proposed synthesis model with scaffolding, a technique
originally intended to facilitate evolution of
recursive programs \cite{Moraglio:2012:CEC}, and
consisting in fetching the desired output from a test
case, rather than calling a function. Experiment
concerning synthesis of list manipulation programs in
Scala allows us to conclude that parallel synthesis
indeed pays off, and that engagement of scaffolding
leads to further improvements.",
