BeforeNotgoalreached

BeforeNotgoalreached is a term used in discussions of goal-oriented systems to denote the state in which an agent has not yet reached its stated goal before a predefined deadline or before another specified condition occurs. The phrase emphasizes the pre-failure phase of task execution and is often used in theoretical analyses and experimental reports to discuss performance under time constraints.

Origin and usage

The term is not part of a single standardized formalism, but it appears in informal analyses, documentation, and discussions about deadline-driven evaluation. It serves to describe pre-goal states and to distinguish them from outcomes where the goal is achieved, or where termination occurs after the deadline for other reasons. It is commonly associated with metrics such as pre-goal failure rate, which counts episodes that end without goal achievement within the allotted time window.

Applications in planning and learning

In planning and reinforcement learning, BeforeNotgoalreached helps separate the impact of time limits and planning horizons from other failure modes. Analysts may examine how changes in computation budget, lookahead depth, or policy effectiveness influence the frequency of pre-goal failures and the overall success rate within deadlines.

Example

In a navigation task with a 60-second limit, episodes where the agent does not arrive at the destination within 60 seconds are classified as BeforeNotgoalreached. Researchers might report the share of such episodes to compare strategies under strict timing constraints.
