A reachability tree for statecharts and analysis of some …
Statecharts are one of the most popular modeling formalisms that is used in a diversity of real world applications, such as cyber-physical systems, mobile computing, and bio-informatics. Following common step-wise refinement strategies, modelers often develop and evolve Statecharts models incrementally to satisfy requirements and changes.
Statecharts | AnyLogic Help
Statechart is used to show the state space of a given algorithm, the events that cause a transition from one state to another, and the actions that result from state change. By using statecharts you can visually capture a wide variety of discrete behaviors, much more rich than just idle/busy, open/closed, or up/down status offered by most block ...

State Machines and Statecharts: What are they?
They are side-effects allowing us to interact with the world outside of the machine itself or to send events to the machine. They are instantaneous and ideally take zero amount of time (you are not waiting for something to be finished, e.g. a request to respond). Think of actions like "fire and forget".
What is a state machine?
An abstract state machine is a software component that defines a finite set of states: One state is defined as the initial state. When a machine starts to execute, it automatically enters this state. Each state can define actions that occur when a machine enters or exits that state. Actions will typically have side effects.

Sismic—A Python library for statechart execution and testing
Sismic provides a modular, easily extensible architecture, summarised in Fig. 1.Experienced Python developers may choose to directly create and manipulate statecharts through the sismic.model API. In practice, it is more convenient to create statecharts using either a text-based markup editor or an external visual editor, and …

Generating statechart designs from scenarios — Monash …
abstract = "This paper presents an algorithm for automatically generating UML statecharts from a collection of UML sequence diagrams. Computer support for this transition between requirements and design is important for a successful application of UML's highly iterative, distributed software development process.

Guard
Guard. Also known as Conditional transition. A guard is a condition that may be checked when a statechart wants to handle an event.A guard is declared on the transition, and when that transition would trigger, then the guard (if any) is checked. If the guard is true then the transition does happen. If the guard is false, the transition is ignored.
On SA-RT and Statecharts for Reactive Systems
The main conclusion are as follows -There can be translation from one model to the other -Statecharts semantics is better and formalised than SA--RT; hence code generation is easily implemented. -control transformation is better expressed with statecharts -Data is better specified with SA-RT -SA-RT is a really software engineering …
Using a process algebra interface for verification and …
Highlights. •. Verification and validation of UML Statecharts are needed due to issues like livelock, inaccessible states, and non-deterministic states. •. Process algebra methods have the abilty to verify and validate UML Statecharts. •. The LOTOS process algebra is used to map and verify and validate the Statecharts.

What Is Data Mining? | IBM
What is data mining? Data mining, also known as knowledge discovery in data (KDD), is the process of uncovering patterns and other valuable information from large data sets. Given the evolution of data warehousing technology and the growth of big data, adoption of data mining techniques has rapidly accelerated over the last couple of decades ...
How to use statecharts
The statechart asks the world about some thing, known as a guard — e.g. is the text field empty, or is the HTTP response complete. The statechart tells your object to perform some action or control some activity — e.g. tell the field that it's "invalid", or start parsing the results, or stop a HTTP request. The statechart tells you ...

Transition
Transition. In an executing state machine, a transition is the instantaneous transfer from one state to another. In a state machine, a transition tells us what happens when an event occurs.. When an event happens, the currently active state(s) are inspected, looking for an outbound transition that could be triggered by the event.

Practical UML Statecharts in C/C++ | ScienceDirect
Description. Practical UML Statecharts in C/C++ Second Edition bridges the gap between high-level abstract concepts of the Unified Modeling Language (UML) and the actual programming aspects of modern hierarchical state machines (UML statecharts). The book describes a lightweight, open source, event-driven infrastructure, called QP that enables ...
Using a statechart increases the number of lines of code
When you solve a problem using a statechart, it forces a certain structure upon the code. For example, since the events should no longer directly cause side effects, the events and those side effects (called actions) might need function signatures, and simply be more "explicit".. This forced structure can increase the number of lines of code somewhat, but …
PLC-Statecharts: An Approach to Integrate UML
This paper presents the core concepts for PLC-statecharts – an adaptation of UML-statecharts – which can be used as a visual programming language for PLCs. They combine the advantages of UML-statecharts with a strict formal basis and can be transparently used in the context of IEC 61131-3 (3 rd Edition). The defined formal …
