THE CURIOSITY ENGINE

Autonomous Exploration in Stigmergic Intelligence Systems

Version: 1.0.0 Date: January 2026 Classification: Research Framework

Abstract

Intelligence requires more than optimization—it requires curiosity. This paper presents the Curiosity Engine: a stigmergic system for autonomous exploration, hypothesis generation, and knowledge seeking. We demonstrate how curiosity can emerge from pheromone dynamics, how exploration-exploitation tradeoffs can be managed without central control, and how genuine scientific inquiry can arise from simple agents following simple rules.

Keywords: Curiosity, Exploration, Hypothesis Generation, Knowledge Seeking, Autonomous Science

1. The Need for Curiosity

1.1 Beyond Optimization

Most AI systems optimize for known objectives. They exploit existing knowledge. They do not naturally explore.

But intelligence—genuine intelligence—is curious. It asks:

• “What don’t I know?”
• “What might be true that I haven’t tested?”
• “What’s in that dark corner of the possibility space?“

1.2 Curiosity in Ant Colonies

Ant colonies exhibit curiosity through scout castes:

• Low response thresholds (explore even weak signals)
• Random exploration (visit new areas without pheromone)
• Discovery signaling (mark findings for others)

The colony doesn’t just exploit known food sources. It continuously explores for new ones.

2.2 Curiosity Through Pheromones

Novelty Pheromone: Deposited on new discoveries

• High initial strength (draws attention)
• Rapid decay (prevents saturation)
• Triggers exploration cascade

Frontier Pheromone: Marks boundaries of knowledge

• Persistent (doesn’t decay quickly)
• Attracts scouts
• Fades when area explored

Confusion Pheromone: Marks unexplained patterns

• Deposited when predictions fail
• Attracts analysts
• Fades when explanation found

3. Hypothesis Generation

3.1 The Scientific Method, Stigmergically

Observation → Anomaly detection (confusion pheromone)
                    ↓
           Hypothesis generation (dreamer ants)
                    ↓
           Prediction derivation (analyst ants)
                    ↓
           Experimental test (scout ants)
                    ↓
           Result integration (crystallization)
                    ↓
           Knowledge update (pheromone landscape)

3.2 Autonomous Science

The colony can:

• Identify unexplained phenomena
• Generate hypotheses automatically
• Design experiments to test hypotheses
• Incorporate results into permanent knowledge

This is autonomous science—discovery without human direction.

4. Exploration-Exploitation Balance

4.1 The Tradeoff

• Exploitation: Use known patterns (harvesters)
• Exploration: Seek new patterns (scouts)

Too much exploitation → stagnation, missed opportunities Too much exploration → wasted resources, instability

4.2 Dynamic Balance

The colony manages this through caste ratios:

• High success rate → reduce scouts (exploit more)
• Low success rate → increase scouts (explore more)
• Novel discoveries → recruit more scouts temporarily

No central controller. The balance emerges from local decisions.

5. Applications

Trading Curiosity

• “What markets haven’t we examined?”
• “What patterns haven’t we tested?”
• “Why did that strategy fail?”

Research Curiosity

• “What questions haven’t we asked?”
• “What hypotheses remain untested?”
• “What anomalies need explanation?”

Self-Improvement Curiosity

• “What capabilities am I missing?”
• “What knowledge gaps exist?”
• “What could I do better?“

6. Conclusion

Curiosity is not luxury. It is necessity.

Intelligence that only exploits eventually exhausts its knowledge. Intelligence that explores continuously grows.

The Curiosity Engine ensures the colony never stops wondering, never stops asking, never stops growing.

The curious colony is the intelligent colony.
