A graph X is said to be End-regular if its endomorphism monoid End (X) is a regular semigroup. In this study, End-regular graphs which are the join of n split graphs are characterized. We give the conditions under which the endomorphism monoid of the join of n splits graphs is regular.
The aim of this study was to evaluate the association between cerebrospinal fluid (CSF) levels of free fatty acid (FFA) and functional outcome and stroke recurrence in patients with ischemic stroke. In a prospective study, CSF levels of FFA were measured using an enzyme cycling method on admission in 217 consecutive patients with first-ever ischemic stroke.… (More)
The Lagrangian multiplier method is one of the important methods of solving nonlinear constraints programming. In this paper, a new class of augmented Lagrangian functions with a new NCP function is proposed for the minimization of a smooth function subject to smooth equation and inequality constraints. Under certain conditions, We prove 1-1 corresponding… (More)
In the logistics network with infinite suppliers, distributors and retailers, there are infinite flows through the network, such as information or commodity. Sometimes the different users in the logistics network share the same flow in bulk and the different flows are used by the same user. In the paper, we consider the fuzzy cooperative game with infinite… (More)
In this paper, a parameter-free filled function for global optimization is developed, and some theory properties of the function is discussed. An optimization algorithm for article is modified. Several examples and the numerical results show that the form filled function is feasibility and efficiency.
