It depends on your utility function. If the utility function is simply the
number of received electrical shocks, then it would be a good idea to
press the buttons as fast as possible.
Typically, people working on algorithm theory want to create programs that
produce solutions to well defined problems as quickly as possible, where
the objective function is typically easy to compute. This and nothing else
is the goal of the Goedel machine Find solutions to hard problems as fast
as possible. The utility function may be a bit different, but it is
always about
performance (speed, memory consumption, quality of solution, etc...)
This may become clear to you if you read the page about the example
applications:
