Use descriptive naming

Choose variable, function, and method names that clearly communicate their purpose and behavior. Avoid ambiguous abbreviations, numbered suffixes, double negatives, and names that don’t accurately reflect functionality.

Key principles:

• Use descriptive names over abbreviated ones: preemptorPodPriority instead of podPriority, candidateHyperNodes instead of reScoreHyperNodes
• Avoid numbered suffixes: ok instead of ok1
• Eliminate double negatives: use nodeIsReady instead of !nodeIsNotReady
• Follow Go conventions: use camelCase, not underscores (filterVictimsFn not preemptable_reclaimable_fn)
• Ensure function names match their behavior: if a function does both predicate and scoring, name it accordingly like checkNodeGPUSharingPredicateWithScore

Example:

// Poor naming
func (pmpt *Action) taskEligibleToPreemptOthers(preemptor *api.TaskInfo) (bool, string) {
    podPriority := PodPriority(preemptor.Pod)  // Unclear whose priority
    // ...
}

// Better naming  
func (pmpt *Action) taskEligibleToPreemptOthers(preemptor *api.TaskInfo) (bool, string) {
    preemptorPodPriority := PodPriority(preemptor.Pod)  // Clear ownership
    // ...
}

Clear naming reduces cognitive load, prevents misunderstandings, and makes code self-documenting for future maintainers.
