A general technique establishes equivalence of deterministic and randomized black-box reductions from complete problems in PPP, PPAD, PPA, and t-PPP to TFNP problems, strengthening known separations to randomized versions.
A review of fitness landscape navigation in evolution that clarifies terminology around epistasis and ruggedness, compares genotype-phenotype and genotype-fitness levels, proposes a new outcome-based navigability measure, and discusses relaxing static landscape assumptions.
