<li><strong>distance/dis</strong> <em>(n×n array/matrix)</em>: Distance between each two nodes(TSP/VRP), from node i to node j.</li>
<li><strong>xi</strong> <em>(1×size(xi) array/matrix)</em>: starting node i if xij == 1. xi == i(Knapsack Problem). NOTE: size(xi) = size(xj)</li>
<li><strong>xj</strong> <em>(1×size(xj) array/matrix)</em>: end node j if xij == j. Null for Knapsack Problem. NOTE: size(xi) = size(xj)</li>
<li><strong>objVal</strong> <em>(double)</em>: the min/max value of the object function.</li>
<li><strong>iterations</strong> <em>(int)</em>: shows how many iterations the algorithm takes.</li>
