Tropical algebraic geometry offers new tools for elimination theory and implicitization. We determine the tropicalization of the image of a subvariety of an algebraic torus under any homomorphism from that torus to another torus.

Abstract A 9-year-old girl presented to dermatology with erythematous scaly patches affecting her legs and arms, hypo­pigmented the trunk. She was otherwise fit well, no preceding illness or new medications. Treatment mometasone 0.1% an emollient unsuccessful. Two years later, she had continued develop hypopigmented patches, as well dark clustered naevi on An incisional biopsy taken from a patc...

Approximate Gaussian Elimination

Variable Elimination (VE) is the most basic one of many Bayesian network inference algorithms. The speed and complexity reasoning mainly depend on order elimination. Finding optimal elimination a Nondeterministic Polynomial Hard (NP-Hard) problem, which often solved by heuristic search in practice. In to improve variable method, minimum, maximum potential, minimum missing edge added methods are...
