A guide to experimental algorithmics by Catherine C. McGeoch

By Catherine C. McGeoch

"Computational experiments on algorithms can complement theoretical research through displaying what algorithms, implementations, and speed-up equipment paintings most sensible for particular machines or difficulties. This e-book publications the reader in the course of the nuts and bolts of the most important experimental questions: What may still I degree? What inputs may still I try out? How do I study the knowledge? Answering those questions wishes rules from set of rules design Read more...

What it the typical broadcast distance? • Real instances are collected from real-world applications. A common obstacle to using these types of instances in algorithmic experiments is that they can be difficult to find in sufficient quantities for thorough testing. • Hybrid instances combine real-world structures with generated components. This approach can be used to expand a small collection of real instances to create a larger testbed. Three strategies for generating hybrid graphs for graph coloring are as follows: (1) start with a real-world instance and then perturb it by randomly adding or subtracting edges and/or vertices; (2) create a suite of small instances from random sections of a large instance; or (3) build a large instance by combining (randomly perturbed) copies of small instances.

If costs double as n doubles, C(n) is linear. 4. To determine whether C(n) ∈ (n log n), divide each measurement by n and check whether the result C(n)/n increments by a constant. 5. If cost quadruples each time n doubles, C(n) ∈ (n2 ). Similar rules can be worked out for other common function classes; see Sedgewick [22] for details. Doubling experiments are valuable for checking whether basic assumptions about performance are correct. For example, Bentley [5] describes a study of the qsort function implemented in the S statistical package.

7. Like Random, this algorithm uses iteration to find better Greedy colorings of G. But instead of starting over with a new coloring at each iteration, IG permutes both the vertices and the colors and recolors G, respecting the old coloring when applying the new coloring. The permutations are selected so that the color count cannot increase at each iteration. This algorithm was one of several evaluated in the DIMACS Challenge on Graph Coloring [17]. The original C implementation may be downloaded from Joseph Culberson’s Web site [11].
