Retraction Notice: Iqbal U, Shoukat IA, Elahi I, Kanwal A, Farrukh B, A. Alqahtani M, Rauf A, Alqurni JS. 2021. Optimal sequence for chain matrix multiplication using evolutionary algorithm. PeerJ Computer Science 7:e395 https://doi.org/10.7717/peerj-cs.395
Following publication of the article (Iqbal et al, 2021), concerns were raised about substantial overlap between this article and a postgraduate thesis authored by a researcher at National University of Computer and Emerging Sciences, Pakistan in December 2019.
The corresponding author claims the published article differs from the postgraduate thesis in source code, methodology, implemented algorithm and results; containing an acceptable level of apparently coincidental text overlap.
Following evaluation by a member of the Editorial Board, it was determined that a high proportion of the text in the published article was inappropriately re-used without citation or permission from the author of the thesis. The plagiarism committee at National University of Computer and Emerging Sciences confirmed this text overlap.
In light of the high level of text overlap that questions the reliability of the published work, PeerJ staff retract this article.
