Atomic Force Microscopy

Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Adaptive Particle Swarm Optimization (APSO) enhances search efficiency and global search capabilities over classical Particle Swarm Optimization (PSO). This adaptive approach improves convergence speed and solution accuracy without adding complexity.

Area of Science:

  • Computational Intelligence
  • Optimization Algorithms
  • Swarm Intelligence

Background:

  • Particle Swarm Optimization (PSO) is a widely used metaheuristic algorithm.
  • Classical PSO can suffer from premature convergence and limited search efficiency.
  • There is a need for improved optimization techniques with faster convergence and better global search.

Purpose of the Study:

  • To introduce an Adaptive Particle Swarm Optimization (APSO) algorithm.
  • To enhance the search efficiency and convergence speed of PSO.
  • To improve the global search capability and solution accuracy of optimization algorithms.

Main Methods:

  • APSO employs a real-time evolutionary state estimation to identify exploration, exploitation, convergence, or jumping out states.

  • Algorithmic parameters (inertia weight, acceleration coefficients) are automatically controlled at runtime based on the estimated state.
  • An elitist learning strategy is applied during the convergence state to help escape local optima.

    • Main Results:

    • APSO demonstrated significantly improved convergence speed compared to classical PSO.
    • The adaptive strategy enhanced global optimality and solution accuracy across benchmark functions.
    • APSO showed increased algorithm reliability in finding optimal solutions.

    Conclusions:

    • APSO offers superior performance over traditional PSO in terms of efficiency, speed, and accuracy.
    • The adaptive parameter control and elitist learning strategy are key to APSO's enhanced performance.
    • APSO provides a more robust and efficient optimization tool with minimal added complexity.
