《符號學》(tochastics):國際概率與隨機過程雜志是世界領先的期刊出版研究，關注隨機過程及其在隨機系統建模、分析和優化方面的應用，即以時空演化和隨機效應存在為特征的過程。發表的文章涉及隨機系統分析、特征問題、隨機建模和識別、優化、濾波和控制的所有方面，以及隨機過程理論的有關問題。該雜志還征集論文，討論隨機過程理論在工程系統、物理和生命科學、經濟學和其他領域的重大應用。歡迎就前沿領域的特別問題提出建議，并應將這些建議提交總編，總編將對此進行審查。近年來，概率論的研究與隨機系統問題之間的相互作用日益增強。隨機學的目的是鼓勵這一趨勢，一方面促進對最新理論發展和應用中出現的數學問題的認識。

tochastics: An International Journal of Probability and Stochastic Processes is a world-leading journal publishing research concerned with stochastic processes and their applications in the modelling, analysis and optimization of stochastic systems, i.e. processes characterized both by temporal or spatial evolution and by the presence of random effects.Articles are published dealing with all aspects of stochastic systems analysis, characterization problems, stochastic modelling and identification, optimization, filtering and control and with related questions in the theory of stochastic processes. The journal also solicits papers dealing with significant applications of stochastic process theory to problems in engineering systems, the physical and life sciences, economics and other areas. Proposals for special issues in cutting-edge areas are welcome and should be directed to the Editor-in-Chief who will review accordingly.In recent years there has been a growing interaction between current research in probability theory and problems in stochastic systems. The objective of Stochastics is to encourage this trend, promoting an awareness of the latest theoretical developments on the one hand and of mathematical problems arising in applications on the other.
