The healthcare impact of the epidemic in india was studied using a stochastic mathematical model. Methods: a compartmental seir model was developed, in which the flow of individuals through compartments is modeled using a set of differential equations. Different scenarios were modeled with 1000 runs of monte carlo simulation each using matlab.

In the field of mathematical optimization, stochastic programming is a framework for modeling optimization problems that involve uncertainty. A stochastic program is an optimization problem in which some or all problem parameters are uncertain, but follow known probability distributions.
Stochastic (from greek στόχος (stókhos) 'aim, guess') refers to the property of being well described by a random probability distribution. Although stochasticity and randomness are distinct in that the former refers to a modeling approach and the latter refers to phenomena itself, these two terms are often used synonymously.
In probability theory and related fields, a stochastic or random process is a mathematical object usually defined as a family of random variables. However, a stochastic process is by nature continuous while a time series is a set of observations indexed by integers.

This primer explains how continuous-time stochastic processes (precisely, brownian motion and other ito diffusions) can be defined and studied on manifolds. No knowledge is assumed of either differential geometry or continuous-time processes. The arguably dry approach is avoided of first introducing differential geometry and only then introducing stochastic processes; both areas are motivated.
