Six Lectures on Modern Natural Philosophyption, collisions and time. We propose a scheduling of communications based on distributed and fast coloring algorithms which require .(1) computational time. As the localization is referred to coarse-grain coordinates, it happens that more than one sensor is associated with the same coordinates, hence leader-election mechanism is considered.

Conversion. The Late Treatises,. We present a polynomial time algorithm that solves . on all input pairs (.,.) where . is a proper interval graph. Thus we identify the first graph class other than trees on which the problem is tractable. As a complementary result, we show that the problem is .-hard on chordal graphs, a superclass of proper interval graphs and trees.

,The (2,1)-Total Labeling Number of Outerplanar Graphs Is at Most Δ?+?2,. satisfy ., where Δ(.) is the maximum degree of ., while they also showed that it is true for . with Δ(.)?≥?5. In this paper, we solve their conjecture completely, by proving that . even in the case of Δ(.)?≤?4 .

On Approximation Complexity of Metric Dimension Problem,lete. In particular, we present a greedy constant factor approximation algorithm for these kind of instances and construct a approximation preserving reduction from the bounded degree Dominating Set problem. We also provide first explicit approximation lower bounds for the Metric Dimension problem restricted to dense and bounded degree graphs.
