  2. Stochastic differential equation - Wikipedia

    en.wikipedia.org/wiki/Stochastic_differential...

    The most common form of SDEs in the literature is an ordinary differential equation with the right hand side perturbed by a term dependent on a white noise variable. In most cases, SDEs are understood as continuous time limit of the corresponding stochastic difference equations.

    en.wikipedia.org/wiki/Software_Design_Description

    A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.

    Consider the primary and ancillary detail of the proposed change. This should include aspects such as identifying the change, its owner(s), how it will be communicated and executed, [8] how success will be verified, the change's estimate of importance, its added value, its conformity to business and industry standards, and its target date for completion.

    The United States Air Force provides a continuum of professional military education at Air University with Basic Developmental Education (BDE), Primary Developmental Education (PDE), Intermediate Developmental Education (IDE), and Senior Developmental Education (SDE). [1]

  7. Euler–Maruyama method - Wikipedia

    en.wikipedia.org/wiki/Euler–Maruyama_method

    In Itô calculus, the Euler–Maruyama method (also simply called the Euler method) is a method for the approximate numerical solution of a stochastic differential equation (SDE). It is an extension of the Euler method for ordinary differential equations to stochastic differential equations named after Leonhard Euler and Gisiro Maruyama. The ...

    Consider the autonomous Itō stochastic differential equation: = + with initial condition =, where denotes the Wiener process, and suppose that we wish to solve this SDE on some interval of time [,]. Then the Milstein approximation to the true solution X {\displaystyle X} is the Markov chain Y {\displaystyle Y} defined as follows:
