Abstract: Automatically selecting suitable computing actions to perform with respect to meeting invitations based on user-specific focus time preferences. Individual users customize their own focus time parameters via a graphical user interface that is provided by a computing-implemented calendar system. An individual user may define focus time parameters that prescribes a scheduled focus time that is static in the sense that it occurs at the same time each day and/or a sliding focus duration that can occur within some broader range of time. Flexibility levels may also be prescribed in association with focus time parameters to indicate how flexible or rigid the individual user is with respect to enforcing his or her focus time parameters. The calendar system selects between predefined actions to perform with respect to meeting invitations addressed to the user and that cannot be accepted without resulting in a violation of the user's previously defined focus time parameters.

Abstract: A server computer system determines an initial configuration of group types of items based on an initial set of constraints. The initial set of constraints pertains to item data for the items and user data for a plurality of users. The system modifies the initial configuration to satisfy one or more rules pertaining to the initial set of constraints to create an optimal configuration of group types. The one or more rules include at least one rule pertaining to eligibility of individual users of the plurality of users to be assigned to one of the group types. The system allocates one of the group types of the optimal configuration of group types to corresponding individual users of the plurality of users and provides data describing the optimal configuration of group types and the allocating of one of the group types to the corresponding individual users to a system.
