Perfect and locally perfect colorings
Journal of Graph Theory, 1995AbstractWe present a new algorithm for coloring perfect graphs and use it to color the parity orderable graphs, a class which strictly contains parity graphs. Also, we modify this algorithm to obtain an O(m2 + n) locally perfect coloring algorithm for parity graphs. © 1995 John Wiley & Sons, Inc.

Cycle-perfect graphs are perfect
Journal of Graph Theory, 1996Given any graph \(G\), the cycle graph \(C(G)\) of \(G\) is defined by letting the vertices of \(C(G)\) be the induced cycles of \(G\); two induced cycles of \(G\) are adjacent in \(C(G)\) if they have in \(G\) at least one edge in common. \(G\) is called cycle-perfect if \(G\) and \(C(G)\) have no chordless cycles of odd length at least five.

IEEE Transactions on Information Theory, 1993
Summary: Given positive integers \(r\), \(s\), \(u\), and \(v\), an \((r, s; u, v)\) perfect map is defined to be a periodic \(r\times s\) binary array in which every \(u\times v\) binary array appears exactly once as a periodic subarray. Perfect maps are the natural extension of the de Bruijn sequences to two dimensions.

Perfect lens with not so perfect boundaries
Optics Letters, 2009In manufacturing left-handed media the interfaces will never be perfect; defects and other disturbances to interfaces and material parameters are unavoidable. We report an analytical calculation of electromagnetic wave propagation through a perfect lens with diffuse boundaries.

Maimonides on Perfecting Perfection
Harvard Theological Review, 2017This article addresses two critical questions concerning Maimonides's views on human perfection at the end of hisGuide of the Perplexed. The first is: For those who have reached the highest category of perfection—intellectual perfection, apprehension of the divine, the divine science—what prescription does Maimonides offer for perfecting that ...

We extend positive supercompilation to handle negative as well as positive information. This is done by instrumenting the underlying unfold rules with a small rewrite system that handles constraints on terms, thereby ensuring perfect information propagation.
