A technical article explores solving the LinkedIn-Queens puzzle using computational approaches including SAT solvers and model checkers. The puzzle requires placing queens on an n×n grid such that each row, column, and colored region contains exactly one queen with no adjacent placements. The author demonstrates solutions using PyEDA for a 4×4 grid and compares this with model checker approaches like Spin and FizzBee.
The article explores theoretical scenarios following a solution to the P=NP problem in computer science. It concludes that in most realistic cases—whether P≠NP is proven, the proof is non-constructive, or the algorithm has impractically high polynomial exponents—nothing would change in practice for cryptography and computing. Only if a practical P=NP algorithm with a low exponent were discovered would security systems face genuine threats.
Notre Dame University will reinstate standardized test score requirements for admissions starting with the 2027-28 cycle, ending a test-optional policy that began in 2020. The university argues that test scores provide additional context for evaluating academic preparation, particularly helping identify qualified applicants from first-generation, low-income, and rural backgrounds. Notre Dame emphasizes scores will be evaluated contextually and reaffirms commitment to affordability through expanded financial aid and free test preparation.
