jumpwise

Jumpwise is a term used in discussions of discrete action modeling, referring to a planning or control approach in which an agent advances through a state space by discrete jumps rather than continuous motion. A jumpwise model defines a set of allowable transitions between states, each with an associated cost or reward, and searches for sequences of jumps that optimize a target objective. Time is typically treated as discrete, and the emphasis is on the structure of the transition relation rather than the dynamics within individual states.

The term is not widely standardized and appears mainly in online discussions and a small number of academic works from the 2020s. It is sometimes used interchangeably with jump-based planning or discretized motion planning, though authors may attach slightly different nuances to the concept. In practice, jumpwise methods are applied where the primary challenge is selecting a chain of viable configurations or waypoints rather than simulating continuous trajectories.

Applications include robotics and game AI where fast, tractable planning is required, as well as certain logistics and scheduling problems that can be modeled as transitions between discrete locations or states. Benefits of a jumpwise approach include reduced computational complexity and clearer guarantees when the transition graph is sparse. Limitations include potential loss of fidelity to continuous dynamics, the need for a well-defined and complete transition graph, and possible combinatorial growth in the number of feasible jumps. The term remains relatively niche and is typically clarified by context. See also discretization, state-space search, motion planning, and Jump Point Search.
