“…Table 4 shows the relation of the works according to the technique used, such as Bayesian networks [46][47][48]63,73,78], Markov chains [22,41,45,49,67,68,74], logistic regression [14,19,[50][51][52]75], differential equations [19,25,31,33,43,[54][55][56]59,60,62,65,69,76,77,79,115], contact networks [19,62,64,70], and machine learning [13,92,93]. The most-used technique is differential equations, while machine learning is presented in five jobs.…”
