Generative Adversarial Gumbel MCTS for Abstract Visual Composition Generation
Addressing the intrinsic difficulty of abstract visual composition, characterized by combinatorial placement, sparse feasible sets, discrete feasibility, and underspecified semantics. Traditional pixel-space generators struggle with hard geometric constraints and limited data.
Our Generative Adversarial Gumbel MCTS (GAG MCTS) framework integrates AlphaGo-style search with explicit geometric reasoning and neural semantics. It enforces feasibility via constraint-based pruning, uses a fine-tuned vision-language model for semantic reward, and refines rewards through adversarial training, outperforming baselines in validity and semantic fidelity under tight constraints.

The Tangram Assembly task challenges models to arrange seven fixed geometric pieces into a target shape described by text, such as 'perched bird'. This task probes joint semantic and geometric competence, highlighting the limitations of methods without explicit search in generating semantically aligned abstract visual concepts under strict constraints.

Achieved validity in Tangram Assembly with GAG MCTS, showcasing robust constraint satisfaction.
| Method | FID | Validity (%) | Human Preference (%) |
|---|---|---|---|
| GAG MCTS (g=0.5) | 17.6 | 98.5 | 39.6 ± 3.9 |
| Diffusion (β=1.0) | 34.0 | 1.6 | N/A |
| Auto-regressive (t=0.5) | 24.5 | 59.3 | 5.2 ± 2.7 |
| GAG MCTS significantly outperforms diffusion and auto-regressive models in validity and semantic fidelity, validated by FID and human studies. | |||
Human Study Validation: GAG MCTS vs. Baselines
A small-scale human study involving 5 participants evaluated 50 pairs of generated and ground-truth Tangram images. Participants chose GAG Muzero's shapes significantly more often (39.6% preference vs. 5.2% for Auto-Regressive), indicating superior semantic alignment with textual descriptions. This highlights GAG MCTS's ability to generate reasonably well-matched abstract visual concepts despite the inherent difficulty and limited data.
The Rectangle Composition task simplifies Tangram by arranging a fixed set of rectangles into a specified rectangular region, satisfying non-overlap constraints. This task investigates how generative models perform under varying problem difficulties, specifically contrasting weak vs. tight geometric constraints. It serves to validate the findings from Tangram Assembly in a more controlled setting.
53.50%
Achieved success rate in Hard Rectangle Composition with GAG MCTS, demonstrating robustness under tight constraints.
| Method | Success Rate (%) |
|---|---|
| GAG MCTS (g=0.5) | 53.50 |
| PPO+adv+mask (Greedy) | 30.00 |
| Diffusion (β=10.0) | 15.50 |
| Auto-reg+mask (Greedy) | 1.50 |
| GAG MCTS maintains high success rates even in hard-constrained rectangle packing, unlike diffusion and auto-regressive methods which falter significantly. | |
In Rectangle Composition, GAG MCTS consistently achieves higher success rates compared to baselines, especially as constraints tighten (hard tasks). Auto-regressive policies underperform, diffusion struggles under tight constraints, and even PPO with adversarial refinement remains insufficient without explicit search. This reconfirms the critical role of constraint-aware search for reliable abstract visual composition.
