The machine is defined by specifying how the components of the state are changed by each of the instructions or rules.

WebA structural operational semantics is defined using a transition system between states. In a programing language, the states are all closed expression in the language, and the final states are values. Formally, we make use of two judgements: e 1 → e 2, stating that expression e 1 transitions to state e 2 in one step
