“…To this day, numerous researchers have addressed this crucial issue: in ecological and environmental domains, there are many models, such as the species diversity index (Spatharis & Tsirtsis, 2013), phytoplankton trophic index (Phillips et al, 2013), the comprehensive nutrition state index (Xu et al, 2012), integrated methodology (Wu et al, 2013), and the eutrophication index (Fertig et al, 2014), etc. Research in informatics also approaches the ecosystems' monitoring, such as genetic algorithm (Song et al, 2012), neural network (Melesse et al, 2008; Yang et al, 2015), fuzzy set theory (Giusti et al, 2011), rough set theory (Yan et al, 2016) and support vector machine (SVM) (Huo et al, 2014) while remote sensing control is now widely used for monitoring blooms such as blue‐green algae (Matthews et al, 2015; Zhou et al, 2018).…”
