27th International Conference on Descriptional Complexity of Formal Systems (DCFS 2026)

The 27th International Conference on Descriptional Complexity of Formal Systems (DCFS 2026) discusses various aspects of formal systems, including their complexity, succinctness, and applications in modeling languages, software, and hardware.

Key Topics

• Succinctness of description of objects, state-explosion-like phenomena
• Automata, grammars, languages and other formal systems; various modes of operations and complexity measures
• Size complexity of formal systems
• Circuit complexity of Boolean functions and related measures
• Trade-offs between computational models and mode of operation
• Structural complexity of formal systems
• Co-operating formal systems
• Applications of formal systems -- for instance in software and hardware testing, in dialogue systems, in systems modeling or in modeling natural languages -- and their complexity constraints
• Complexity aspects related to the combinatorics of words
• Size or structural complexity of formal systems for modeling natural languages
• Structural complexity as related to descriptional complexity
• Descriptional complexity in resource-bounded or structure-bounded environments
• Universality and reversibility
• Frontiers between decidability and undecidability
• Blum Static (Kolmogorov/Chaitin) complexity, algorithmic information
• Nature-motivated (bio-inspired) architectures and unconventional models of computing
