TTCS: Test-Time Curriculum Synthesis for Self-Evolving

Chengyi Yang, Zhishang Xiang, Yunbo Tang et al.

What this work does

Co-optimizes a test-question-conditioned curriculum synthesizer and solver using self-consistency and a difficulty signal favoring partially solvable generated questions.

Connection to discovery

A candidate for generating locally useful training problems when a target research problem is too difficult to produce positive rollouts directly.

Evidence

Inspected the variance-based curriculum reward and math-benchmark comparisons against TTRL and sampling baselines.

Scope and limitations

Answer agreement is not independent correctness. A scientific version needs external experimental/verifier signals and checks against a synthesizer/solver reinforcing shared misconceptions.
