COMPUTATIONAL COMPLEXITY / AUG 2026

Adversarial Proof Engineering
for P versus NP

I examined 11 possible approaches to P versus NP and tested the assumptions each one needs. The paper shows where several approaches fail, gives counterexamples, and explains what remains unproved.

This work does not solve P versus NP.

6,794Boolean distinguishers checked against a rational certificate using exact arithmetic.

QUANTITATIVE FINANCE / JUL 2026

Dual-Cadence
Equity Rotation

I tested a rule-based portfolio that reviews some stocks weekly and others monthly. When a stock fails its trend test, that part of the portfolio moves to a Treasury fund or cash.

The backtest includes trading costs, whole shares, and next-open execution. It also examines data limitations and how sensitive the results are to different assumptions.

8Portfolio allocations with weekly or monthly review schedules.
