MCEC: An android tournament

[Joseph]

​ The Mobile Chess Engine Circuit (MCEC) is a passion-driven, hobbyist Android tournament inspired by elite desktop events like TCEC and the Chess.com Computer Chess Championship (CCC).

​Born out of curiosity, MCEC explores a fascinating question: How do the world's strongest chess engines actually perform when constrained to a practical, daily-use mobile phone?

​Unlike massive desktop server setups that brute-force thousands of games overnight, MCEC games are run selectively during free time when the device is available. It is a real-world, practical exploration of software efficiency under strict resource limits.


​ MCEC Circuit History

• ​Season 1 (Completed & Success): Established the core structural proof-of-concept for high-stakes mobile tournament ladders on everyday hardware. The format proved highly competitive and successfully ranked our original mobile engine pool.

• ​Season 2 (Halted / Stopped): Due to technical adjustments, real-world scheduling limitations, and the evolution of the mobile engine landscape, Season 2 was prematurely stopped to recalibrate the entire ecosystem.

• ​Season 3 (Now Beginning!): Rebuilt, optimized, and officially launching. Season 3 implements an expanded 72-engine baseline benchmark, strict stability filters, and a clean CCC-style tier framework to accommodate powerful newcomers.


​ Tournament Goals & Focus

• ​The Low-End Gauntlet: To document how elite, world-class chess engines scale down and perform under limited mobile resources.

• ​Elite Threshold: Exclusively features the strongest open-source chess engines capable of reaching 3300+ to 3400+ Elo environments.

• ​The Stability Filter: MCEC is as much about compatibility, stability, and efficiency as it is about raw strength. Engines must handle mobile thermal conditions and OS constraints without crashing.

• ​Performance Tracking: Rather than calculating official Elo ratings (due to the practical limits of resource-constrained testing), MCEC focuses on head-to-head performance data, structural stability, and mobile win-probabilities.

Special Acknowledgments

​MCEC would not be possible without the incredible support and dedication of the computer chess community. Heartfelt thanks go to:

• ​Jim Ablett: Whose legendary, high-performance Android engine builds form the absolute backbone of this circuit.

• ​Archimedes: For providing specialized, highly-optimized Android engine compilations.

• ​The Engine Developers: The brilliant minds behind the open-source codebases pushing the boundaries of chess science.

• ​Joseph: A fantastic fellow Android tester whose shared knowledge, advice, and testing assistance have been invaluable to the circuit.


​ Our Mission

​MCEC is ultimately a project driven by curiosity, learning, and a profound appreciation for computer chess. By testing, competing, and documenting these battles on a mobile platform, MCEC aims to contribute in its own unique way to the preservation, understanding, and enjoyment of chess engine development on everyday consumer hardware.

MCEC Season 3: Initial Benchmarking Phase Update
​The massive 70-engine baseline benchmark is nearing its conclusion! As a reminder, this is not the main event, but an initial sorting phase to establish our Master Ranks and filter out any unstable engine builds under strict mobile constraints.

​Please note that because this is an unrated, wide-open testing phase using an older mobile GUI, some results may look slightly distorted due to minor GUI processing errors and individual engine bugs. These stability hurdles are exactly what this phase is meant to catch, and they will be handled much better moving into the upcoming official league stages!


​ Technical Alert: Cataphract 1.4 Status
​Cataphract 1.4 Dotprod finishes this phase with 0 points.

​Behavior Log: Right after the 8-move opening book phase ends, the engine successfully makes exactly one move on its own calculation, and then completely stops calculating or communicating with the GUI forever, eventually losing on time every game. It will be removed from active competition until a more stable Android build is available.
