What this evaluates

Tests an agent's capacity to handle complex constraint satisfaction by managing and resolving conflicting schedules derived purely from raw natural language descriptions. It simulates personal assistant scenarios where the model must maintain a high-density representation of events to detect conflicts accurately.

Datasets

• Calendar Scheduling — total ?; splits: test (-1)

Metrics

• Exact Match (EM) (primary) — range: [0, 1]
  • 1 if the predicted schedule exactly satisfies all constraints and matches the ground-truth solution, 0 otherwise.

Input / output format

Input: Raw natural language descriptions of scheduling constraints and events.

Output: A final schedule or decision satisfying the target constraints.

Scoring recipe

def score_em(pred, gold):
    return 1.0 if pred.strip().lower() == gold.strip().lower() else 0.0

# Average over test set
em_scores = [score_em(p, g) for p, g in zip(predictions, gold_answers)]
final_metric = sum(em_scores) / len(em_scores)

Common pitfalls

• Frequent context switching in agentic baselines (e.g., ReAct) can fragment constraint tracking and introduce noise.
• Smaller models struggle significantly with multiple simultaneous constraints, often requiring explicit cache mechanisms to maintain performance.
• Zero-shot extraction scenarios may be sensitive to prompt structure, causing minor baselines to occasionally outperform more complex methods.

Evidence (verbatim from paper)

For TACT and Calendar Scheduling, we report Exact Match (EM), which directly measures whether the produced answer satisfies the target decision/constraints.
