Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

PANORAMEX — named after Panoramix, the druid character from the Asterix and Obelix comic strip — uses the RAVE UCT formula (Gelly and Silver, 2007) with UCB exploration constant 0 and the save-bridge pattern in simulations. PANORAMEX ran on an 18-node cluster of 4-core machines, using root parallelization and majority vote to select each move. This yielded about 6×10 5 simulations per second. WOLVE, the 2010 silver medallist (Arneson, Hayward, and Henderson, 2010) 2, uses truncated-width alpha-beta search, a Shannon-style electric circuit evaluation function with cell adjacencies augmented by virtual connections, and pruning of inferior cells. To save time, WOLVE uses a book built by caching 6-ply moves. This year Broderick Arneson added pondering and changed the search algorithm from fixed-ply to variable-ply with timemanaged iterative deepening. WOLVE used 2 threads (one to select moves, one to solve) on a 4-core machine, reaching 6-ply on most moves. MOHEX, the 2010 gold medallist (Arneson et al., 2010), is a Monte Carlo tree search program built on the code base of FUEGO, the Go program developed by Martin Müller, Markus Enzenberger and others at the University of Alberta. FUEGO uses lock-free parallelization (Enzenberger and Müller, 2009), and backs up virtual losses for better parallelization. MOHEX computes virtual connections and inferior cells in UCT tree nodes visited at least 400 times. This year Arneson added pondering, Huang helped with tuning, and Pawlewicz improved the

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
