      Infix Notation We write expression in infix notation, e.g. a - b + c, where operators are used in-between operands. Prefix Notation In this notation, operator is prefixed to operands, i.e. operator is written ahead of operands. For example, +ab. This is equivalent to its infix notation a + b.

Infix Notation
We write expression in infix notation, e.g. a - b + c, where operators are used in-between operands.

Prefix Notation
In this notation, operator is prefixed to operands, i.e. operator is written ahead of operands. For example, +ab. This is equivalent to its infix notation a + b. Prefix notation is also known as Polish Notation.

Postfix Notation
This notation style is known as Reversed Polish Notation. In this notation style, the operator is postfixed to the operands i.e., the operator is written after the operands. For example, ab+. This is equivalent to its infix notation a + b.

Stochastic programs are mathematical programs that involve data that is not known with certainty. Deterministic programs are formulated with fixed parameters, whereas real world problems frequently include some uncertain parameters. Often these uncertain parameters follow a probability distribution that is known or can be estimated. Thus stochastic programs approximate unknown data by probability distributions. The goal is to find some policy that is feasible for all (or almost all) the possible data instances and that maximizes the expectation of some function of the decision variables and the random variables.
