We will now see a simple rule that can make sure we do not cycle. Definition 1 (Bland's least index rule). If there is a choice of entering variables (i.e., there are several j such that ¯cj < 0), choose the variable with the smallest index, (i.e., we choose index j∗ = min{j : ¯cj < 0}).
The least-index primal simplex rule makes the selection of both the entering and the leaving variable uniquely determined. Least-index rules are based on ...
