Property testing is a relaxation of decision problems

in which it is required to distinguish {\sc yes}-instances

(i.e., objects having a predetermined property) from instances

that are far from any {\sc yes}-instance.

We presents three theorems regarding testing graph

properties in the adjacency matrix representation. ...

In this paper we consider two refined questions regarding

the query complexity of testing graph properties

in the adjacency matrix model.

The first question refers to the relation between adaptive

and non-adaptive testers, whereas the second question refers to

testability within complexity that

is inversely proportional to ...

We initiate a systematic study of a special type of property testers.

These testers consist of repeating a basic test

for a number of times that depends on the proximity parameters,

whereas the basic test is oblivious of the proximity parameter.

We refer to such basic ...

Referring to the query complexity of property testing,

we prove the existence of a rich hierarchy of corresponding

complexity classes. That is, for any relevant function $q$,

we prove the existence of properties that have testing

complexity Theta(q).

Such results are proven in three standard

domains often considered in property ...

Detecting and counting the number of copies of certain subgraphs (also known as {\em network motifs\/} or {\em graphlets\/}), is motivated by applications in a variety of areas ranging from Biology to the study of the World-Wide-Web. Several polynomial-time algorithms have been suggested for counting or detecting the number of ... more >>>

The aim of this article is to introduce the reader to the study

of testing graph properties, while focusing on the main models

and issues involved. No attempt is made to provide a

comprehensive survey of this study, and specific results

are often mentioned merely as illustrations of general ...

The standard definition of property testing endows the tester with the ability to make arbitrary queries to ``elements''

of the tested object.

In contrast, sample-based testers only obtain independently distributed elements (a.k.a. labeled samples) of the tested object.

While sample-based testers were defined by

Goldreich, Goldwasser, and Ron ({\em JACM}\/ ...

Fine-grained reductions, introduced by Vassilevska-Williams and Williams, preserve any improvement in the known algorithms. These have been used very successfully in relating the exact complexities of a wide range of problems, from NP-complete problems like SAT to important quadratic time solvable problems within P such as Edit Distance. However, until ... more >>>

We initiate a study of testing properties of graphs that are presented as subgraphs of a fixed (or an explicitly given) graph.

The tester is given free access to a base graph $G=([\n],E)$, and oracle access to a function $f:E\to\{0,1\}$ that represents a subgraph of $G$.

The tester is ...

We consider two versions of the problem of testing graph isomorphism in the bounded-degree graph model: A version in which one graph is fixed, and a version in which the input consists of two graphs.

We essentially determine the query complexity of these testing problems in the special case of ...
