Cliques and Clique Covers in Interval-Valued Fuzzy Graphs
Finding cliques and clique covers in graphs are one of the most needful tasks. In this paper, interval-valued fuzzy cliques (IVFQs) and interval-valued fuzzy clique covers (IVFQCs) of an interval-valued fuzzy graph (IVFG) are introduced by introducing ...

Interval Count of Interval Graphs
The interval count problem is that of determining the smallest number of distinct interval lengths that is sufficient to represent an interval model of a given interval graph. The class of interval graphs is well known, with several applications. This article briefly summarizes my doctorate thesis done on the subject with supervision of Prof.

The LexCycle on $\overline{P_{2}\cup P_{3}}$-free Cocomparability Graphs [PDF]
A graph $G$ is a cocomparability graph if there exists an acyclic transitive orientation of the edges of its complement graph $\overline{G}$. LBFS$^{+}$ is a variant of the generic Lexicographic Breadth First Search (LBFS), which uses a specific tie ...

Interval Edge-Colorings of Cartesian Products of Graphs I
A proper edge-coloring of a graph G with colors 1, . . . , t is an interval t-coloring if all colors are used and the colors of edges incident to each vertex of G form an interval of integers.

Minimum 2-Tuple Dominating Set of an Interval Graph
The -tuple domination problem, for a fixed positive integer , is to find a minimum size vertex subset such that every vertex in the graph is dominated by at least vertices in this set.

Strong Interval – Valued Pythagorean Fuzzy Soft Graphs
A Strong interval – valued Pythagorean fuzzy soft sets (SIVPFSS) an extending the theory of Interval-valued Pythagorean fuzzy soft set (IVPFSS). Then we Propose Strong interval valued Pythagorean fuzzy soft graphs (SIVPFSGs).

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

A linear time algorithm to compute square of interval graphs and their colouring
The square of a graph G=(V,E), denoted by G2, is a graph on the same vertex set V(G) such that two vertices x and y are adjacent in G2 if and only if there is a path of length one or two between x and y in G.

Coloring problem of signed interval graphs [PDF]
A signed graph $(G,\sigma)$ is a graph together with an assignment of signs $\{+,-\}$ to its edges where $\sigma$ is the subset of its negative edges.

Open-interval graphs versus closed-interval graphs
It is proved that a countable graph is a closed-interval graph if and only if it is an open-interval graph. A counter-example is given for uncountable graphs. Also the case of unit length intervals is studied.
