Roderick G. Lamond,Norman L. Chaterinent next to the density question for the different graph classes. For 1-planar graphs, the recognition problem has been settled, namely it is NP-complete for the general case, while optimal 1-planar graphs, i.e. those with maximum density, can be recognized in linear time. For 2-planar graphs, the

Ralph T. Manktelow M.D., F.R.C.S.(C)d Gotsman, which is in turn based on Floater’s asymmetric extension of Tutte’s classical spring-embedding theorem..First, we give a very simple algorithm to construct piecewise-linear morphs between planar straight-line graphs. Specifically, given isomorphic straight-line drawings . and . of the sam

Measurement of Active Circuits,We consider the problem of drawing an outerplanar graph with . vertices with at most one bend per edge if the outer face is already drawn as a simple polygon. We prove that it can be decided in .(.) time if such a drawing exists, where . is the number of interior edges. In the positive case, we can also compute such a drawing.
