Greedy search algorithm is an effectual tool, which is generally used for optimization problems. The important steps of all greedy algorithms are as follows: 1. Choosing a candidate set and dividing the main problem into a finite set of subproblems. For the first subproblem, arbitrarily a candida...
) and hence are not so easy for solvers and programs that calculate the independence number. Furthermore, fullerenes are often of type II. The algorithm Min-SP produced the following upper bounds: \alpha (F_{20} \boxtimes F_{20})\geqslant 56, ...
In Section 4, we use Theorem 3.2 to prove convergence for two popular classes of greedy algorithms: the β-greedy algorithm (Theorem 4.1) and the geometric greedy algorithm of [4] (Theorem 4.2). Supporting numerical results on kernel-based interpolation from scattered Radon data are presented ...
FJSP benchmarks have been conducted. By compared with other algorithms, the experimental results show that the presented algorithm is competitive and able to find global optimum for most instances. The simplicity of the proposed IG provides an effective method that is also easy to apply and ...

We present an algorithm whose space usage isΘ(n)whereas existing algorithms useΘ(n2)space, while being only a logarithmic factor slower than the fastest known algorithm, thus answering a question left open in [2]. Our algorithm makes the greedy spanner practical to compute for much larger in...
Clearly, virtual coordinates need not to reflect the nodes actual positions and, hence, they can be suitably chosen to guarantee that the greedy routing algorithm succeeds in delivering packets. After the publication of [13], intense research efforts have been devoted to deter- mine: (i) Which...
Algorithm 1 Sequential relaxation for (2) (“Gauss-Seidel” if H = D− 1B). Full size image Each update from k to k + 1 is termed one relaxation, and n such relaxations, since they are done one after the other, correspond to one iteration m in (2) with H = (D − L...
We state our main result Theorem2.1in Sect.2; in particular this section also contains in Sect.2.3the definition of the sequences used to characterise the output of the greedy algorithm of Steinerberger as well as an outline of our proof strategy. In Sect.3, we review properties of the va...
