,Plane Multigraphs with?One-Bend and?Circular-Arc Edges of?a?Fixed Angle,on, we improve upon bounds for the number of edges in . graphs (i.e., graphs that can be drawn in the plane with one-bend edges such that any two crossing edges meet at angle .). This is the first improvement on the size of . graphs in over a decade.

,Minimizing Corners in?Colored Rectilinear Grids,alization, prove that it is .-hard even for ., and present an exact dynamic programming algorithm. Together with a set of simple kernelization rules, this leads to an .-algorithm in the number of colored cells of the input. We additionally provide an .-algorithm in the solution size, and a polynomial .-approximation algorithm.
