Tariff evaluations of 0.0 for TOU tariffs #763

Closed jecollins closed 10 years ago

jecollins commented 10 years ago

We are seeing occasional cost estimates of 0.0 from the household and officecomplex customer models when evaluating time-of-use tariffs. This does not appear to happen immediately in a game, but rather after several evaluations. Once it starts happening, it seems to be repeated on other tariffs. It is observable in games 115 and 155 of the 2014 Qualifying rounds.

Here's an example from the trace log in game 155:

An array should have been copied, and was being smashed. Fixed, tested, deployed.
