The following article continues my understanding and impression of algorithms whose origin is based on the beauty of nature and physical phenomena. Harmony search (HS) is a meta-heuristic search algorithm that mimics the improvisation process of musicians in finding a pleasing harmony. In the process of improvising music, a set…

In this article, an artificial hummingbird algorithm (AHA), a nature-inspired optimization method, is put forth to address optimization issues. The AHA algorithm mimics the unique flying abilities and intelligent foraging techniques of hummingbirds. Axial, diagonal, and omnidirectional flights are three types of flying abilities used in foraging tactics that are…

In my previous articles, I displayed nature-based algorithms to solve optimization problems both in engineering and robotics domains. Since these algorithms solve optimization problems as required however there is often a need for parameter tuning. …

When you run your ROS2 application, there are often requirements to run ROS2 nodes in different locations on different machines. Since ROS2 uses in the abstract DDS layer for communication between the nodes, we can arrange the communication very easily. …

The following article provides you with general intuition over the Behaviour Trees which are often used in robotic applications or frameworks: ROS, Moveit, and NAV2. Understanding the principles of the Behavior Tress (BT) framework gives you an excellent opportunity to apply knowledge in the gaming domain. …

The following article depicts the simple numerical methods to compute derivatives in C++. I am going to focus on robotic applications and simply describe how to compute velocity, acceleration, and jerk while robots move along the path with certain time constraints. The computational methods for obtaining the high-order derivatives are not…

The following article presents the Sine Cosine Algorithm (SCA) for solving optimization problems with constraints. The algorithm was pioneered by Seyedali Mirjalili. The SCA uses a mathematical model based on sine and cosine functions to generate many initial random solutions (objective function). Then, the algorithm randomly varies the solution either outwards…

In the following article, I will display general problems, which often occur while compiling/running the C++ application (program). Since there are many types of errors, having different roots I will focus only on the general approach and depict standard commands to analyze the root. …

Software testing is the process of evaluating and confirming that a software application or product using software modules performs as intended. Testing has advantages such as bug detection, decreasing development costs, and finally affects better performance. The following article describes simple steps allowing you to run GoogleTest in your C++…
