Difference Equation Solution using z-Transform

Difference Equation Solution using z-Transform

The z-transform is a powerful tool for analyzing practical discrete-time systems, often represented by linear difference equations. Solving a higher-order difference equation requires knowledge of the input signal and the initial conditions up to one term less than the order of the equation.
The z-transform facilitates handling delayed signals by shifting the signal in the z-domain, which corresponds to delaying the signal in the time domain, and advancing signals by similarly shifting in the...

Area of Science:

Computational Intelligence
Optimization Algorithms
Metaheuristic Computing

Background:

The Zebra Optimization Algorithm (ZOA) faces limitations in late-stage optimization, local optima avoidance, convergence speed, and exploration.
Existing metaheuristic algorithms often struggle with premature convergence and insufficient global search capabilities.

Purpose of the Study:

To enhance the Zebra Optimization Algorithm (ZOA) by integrating opposition-based learning and a dynamic elite-pooling strategy, creating the OP-ZOA.
To improve ZOA's late-stage optimization, local optima escape, convergence speed, and exploration capabilities.

Main Methods:

Implemented opposition-based learning for population initialization to increase diversity and escape local optima.
Introduced a real-time information synchronization mechanism between the best (Xbest) and worst (Xworse) individuals to enhance global search.
Developed a dynamic elite-pooling strategy with three fitness factors for updating the optimal individual's position, boosting robustness.

Main Results:

OP-ZOA demonstrated superior performance against seven other metaheuristic algorithms on the CEC2017 test functions.
Significantly improved efficiency in optimizing the artificial potential field (APF) method, reducing local optimum convergence issues.
Achieved faster iteration speeds and an average reduction of 7.55175 m (16.291%) in planned path length after escaping local optima.

Conclusions:

OP-ZOA offers enhanced optimization capabilities, significantly improving escape efficiency from local optima and solution reliability.
The proposed algorithm provides a more robust and efficient approach to complex optimization problems compared to existing methods.
