Consider the following linear program in standard form min{x1 – 2x2 + x3 – 2x4 : x1 + x2 + 2x3 + x4 = 4; -x1 – 2x2 + x3 + x4 = 2; x> 0} and the vertices (a) âî = [0,0, 2, 0]" . (b) âêt = [1,0, 0, 3]", (c) & = [0,2/3,0, 10/3]T. You can assume that the coefficient matrix A has full row rank. For each vertex, decide whether the vertex is optimal or not, and whether it is degenerate or not.

Consider the following linear program in standard form min{x1 – 2x2 + x3 2x4 : x1 + x2 + 2x3 + x4= 4; -x1 – 2x2 + x3 + x4 = 2; x > 0} | and the vertices (a) â = [0,0, 2, 0]". (b) ât = [1,0, 0, 3]", (c) & = [0,2/3,0, 10/3]". You can assume that the coefficient matrix A has full row rank. For each vertex, decide whether the vertex is optimal or not, and whether it is degenerate or not.
