We show that with .(.log .) edge flips and point moves, we can transform any geometric near-triangulation on . points to any other geometric near-triangulation on . possibly different points. This improves the previously known bound of .(..) edge flips and point moves.

Paul Pop,Wajid Hassan Minhass,Jan Madsengorithms are based on two principles: embedding the state transition graph in a low-dimensional integer lattice and projecting the lattice onto the plane, or drawing the medium as a planar graph with centrally symmetric faces.

Chuanliang Feng,Xiaoqiu Dou,Yibin XuWe prove that the number of distinct weaving patterns produced by . semi-algebraic curves in ?. defined coordinate-wise by polynomials of degrees bounded by some constant ., is bounded by 2., where the implied constant in the exponent depends on .. This generalizes a similar bound obtained by Pach, Pollack and Welzl [3] for the case when .=1.
