“…These strategies can be either deterministic or non-deterministic , Cohen, et al, 1997;Lei, et al, 2008. Some of the combinatorial strategies adopted metaheuristics algorithms for searching the test space , Ahmed, et al 2012;Alsewari and Zamli, 2012;Hazli, et al, 2012;Rahman, et al, 2014;Yang, et al, 2014;Ahmed, et al, 2015;Prasad, et al, 2015;Zamli, et al, 2016;Rabbi, 2017;Zamli, et al, 2017;Nasser, et al, 2018. Due to the NP-Hard problem, Colburn makes a dedicated website to record minimal upper bound for CA ,Colbourn, 2019. Earlier works also reported that the number of tuples increased significantly when increased the number of parameters and/or the strength of coverage and/or the parameter-values.…”
