The State Complexity of L
نویسنده
چکیده
We show that if M is a DFA with n states over an arbitrary alphabet and L = L(M), then the worst-case state complexity of L2 is n2 − 2n−1. If, however, M is a DFA over a unary alphabet, then the worst-case state complexity of L is kn− k + 1 for all k ≥ 2.

Reduction of Computational Complexity in Finite State Automata Explosion of Networked System Diagnosis (RESEARCH NOTE)
This research puts forward rough finite state automata which have been represented by two variants of BDD called ROBDD and ZBDD. The proposed structures have been used in networked system diagnosis and can overcome cominatorial explosion. In implementation the CUDD - Colorado University Decision Diagrams package is used. A mathematical proof for claimed complexity are provided which shows ZBDD ...
متن کاملSyntactic Complexity of Russian Unified State Exam Texts in English: A Study on Reliability and Validity
In this study we analyze texts used in Russian Unified State Exam on English language. Texts that formed small research corpora were retrieved from 2 resources: official USE database as a reference point, and popular website used by pupils for USE training “Neznaika” (https://neznaika.pro/). The size of two corpora is balanced: USE has 11934 tokens and “Neznaika” - 11918 tokens. We share Biber’...
متن کاملA Novel Method for Detection of Epilepsy in Short and Noisy EEG Signals Using Ordinal Pattern Analysis
Introduction: In this paper, a novel complexity measure is proposed to detect dynamical changes in nonlinear systems using ordinal pattern analysis of time series data taken from the system. Epilepsy is considered as a dynamical change in nonlinear and complex brain system. The ability of the proposed measure for characterizing the normal and epileptic EEG signals when the signal is short or is...

Conflict is inevitable in the organization. Neglecting confliction. Neglecting conflict will result in adverse political, social, and economic impacts,destroying the organization's balance and dynamism. The ultimate aim of the present study is as follows: assessing the status quo and measuring the job conflicts among employees of state-owned bodies evaluating the organization from the three di...
متن کاملInvestigating the relationship among complexity, range, and strength of grammatical knowledge of EFL students
Assessment of grammatical knowledge is a rather neglected area of research in the field with many open questions (Purpura, 2004). The present research incorporates recent proposals about the nature of grammatical development to create a framework consisting of dimensions of complexity, range and strength, and studies which dimension(s) can best predict the stat...
متن کاملP-57: The Beneficial Adipokines in Reproductionand Infertility
Background: Adipokins are cytokines predominantely or exclusively expressed by adipose tissue that circulate and affect target tissues. Four known adipokines, adiponectin, visfatin/PBEF, omentin and vaspin, all increase tissue sensitivity to insulin, and are thus described as ’beneficial’. In this review such biological actions and potential roles of the adipokines leptin, adiponectin and resis...
