Analysis Says Tree Search and Monte Carlo Control Share a Core
A conceptual note argues that Monte Carlo Tree Search can be understood as every-visit Monte Carlo control when the comparison is limited to trajectory sampling and Monte Carlo action-value updating. The claim clarifies terminology and computational scope, but does not compare performance.

Flow-matching shortcuts aid training but miss exact likelihoods
A theoretical and synthetic analysis finds that conditional flow matching can replace endpoint likelihood calculations only when specific residual errors cancel. In on-policy training, the shortcut may still improve reward even when its likelihood ratios are far from exact.
