Abstract: The presentation includes a detailed discussion of my Doctoral
research based on the development and applications of efficient
metaheuristic algorithms for solving constrained optimization problems
(COPs). The primary focus is on the Quadratic Approximation guided Jaya
Algorithm (JaQA) and its enhanced variant, the Self-Adaptive
Multi-Population Quadratic Approximation guided Jaya (SMP-JaQA). These
two algorithms address challenges in solution diversity and balancing
exploration-exploitation, making them highly effective in solving
complex real-world optimization problems. The presentation begins with
an introduction to COPs and the significance of metaheuristics in
overcoming traditional optimization limitations. A comprehensive
discussion on the research motivation, problem statement, and the
identified gaps in existing methodologies follows. The design and
implementation of these two proposed methodologies is elaborated upon,
along with their computational complexity analysis. Experimental
validation is carried out using constrained benchmarks from CEC 2006,
CEC 2010, and CEC 2017. The outcomes demonstrate the superior
performance of the proposed algorithms when compared to state of-the-art
techniques, validated through statistical analysis (say, Friedman Rank
Test and Wilcoxon Signed Rank Test), exploration-exploitation analysis,
convergence analysis, etc. Real-life applications of the research are
also highlighted in areas such as single-stage and two-echelon uncertain
Fixed Charge Transportation Problems (FCTP), dairy feed ration
optimization, mechanical design and electronics design optimization. The
discussion concludes with an overview of research contributions, key
findings, and potential future research directions. Moreover, insights
into the publication status of my research so far is also provided
showcasing peer-reviewed journal and conference publications along with
communicated works.
