The operational semantics should preferably be described in a way that it also captures the time and memory complexity of an execution. It does not have to be a detailed description of how things are actually implemented but it should give an understanding of the execution to allow a programmer to reason about the efficiency of a particular program.

When CSE 6341 3 Operational vs. Axiomatic Operational semantics Explicitly describes the effects of program constructs on program state Shows not only whatthe program does, but also howit does it Essentially describes an interpreter Axiomatic semantics Describes properties of program state, using first-order logic Concerned with constructing proofs for such operational semantics An approach to the semantics of programming languages that uses the concept of an “abstract machine” that has a state and some primitive instructions or rules that cause the states to change. The machine is defined by specifying how the components of the state are changed by each of the instructions or rules. Computations are sequences of state transitions.

Operational Semantics and Program Equivalence. Andrew M. Pitts.
Since this semantics is not sufficient to cover concurrency, search strategies, or to reason about costs associated to particular computations, we define a "small-step" operational semantics

The MB driver model assumes non-blocking operational semantics between the MB Service and miniport drivers by using the asynchronous notification mechanism provided in NDIS 6.x. Notation 3 Logic This article gives an operational semantics for Notation3 (N3) and some RDF properties for expressing logic. These properties, together with N3's extensions of RDF to include variables and nested graphs, allow N3 to be used to express rules in a web environment.
The idea is that P → Q, pronounced “P reduces to Q“, is the same as P τ Q The difference is that reductions are inferred directly from the syntax of the agent, as opposed to τ-transitions which are inferred from input and output transitions.

Operational semantics, a fundamental tool in lan-guage design and verification, provides a formal de-scription of the behaviour of programs. It is often defined in terms of atomic, elementary transitions, de-scribing local behaviour. Mathematically, these trans-
