Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article discusses the complexities of electricity distribution networks and the need for sophisticated protective relay systems to ensure reliable power supply. It introduces an enhanced human conception optimizer (EHCO) algorithm to address the over-current relay coordination problem. EHCO builds upon the Human Conception Optimization (HCO) algorithm by incorporating a wavelet mutation strategy to enhance exploration and exploitation, making it effective in high-dimensional power networks. The article provides a detailed explanation of the EHCO algorithm, its application to relay coordination problems, and its validation through simulations and case studies. The results demonstrate EHCO's superior performance in minimizing relay operating time and avoiding local optima, making it a valuable contribution to the field of power system optimization.
