Abstract: A computer is used for obtaining information about a plural number of energy-saving measures. This can include information about costs of combinations of said energy-saving measures, said costs include first information about costs of making the measures, second information about rebates for the measures, and third information about energy-saving that will occur from the measures, where at least some of said third information will depend on said combinations of said energy-saving measures. An iterative algorithm is used which determines combinations and which determines which of the combinations produce maximum savings by combinations of the said first, second and third information. A report can be created.

Abstract: The present disclosure includes systems and techniques relating to simulating dialog in electronic games. In general, in one implementation, the technique includes: receiving a player interruption signal during presentation of a speech by a machine-controlled character in an electronic game, modifying a state of the machine-controlled character based on a time of the received player interruption relative to a length of the speech, and generating an action of the machine-controlled character based on the modified state. Modifying the state of the machine-controlled character can include adjusting an attitude variable of the machine-controlled character based on the time of the received player interruption, selecting a location in a dialog tree for the machine-controlled character based on the time of the received player interruption, or both.
