“…Two objectives are considered in the second model as maximizing the total profit and minimizes the time and cost by adding the three parameters ( Deb & Sinha, 2009 ). Moreover, many other variants are added in traveling thief problem to solve this by molded the problem in other dimensions that is, Multiple Knapsack Problem ( Lalami et al, 2012 ), multi-objective knapsack ( Bazgan, Hugot & Vanderpooten, 2009 ), fractional knapsack ( Ishii, Ibaraki & Mine, 1977 ), bi-level knapsack ( Chen & Zhang, 2013 ), etc. After this, the benchmark is designed with different algorithms to solve TTP but these are the simple techniques to verify this problem ( Polyakovskiy et al, 2014 ).…”
