A certаin integer prоgrаmming prоblem is а maximizatiоn problem in 4 variables, x1, x2, x3, x4, all of which are binary. One of the constraints in this problem is: 3x1 + 2x2 - x3 + 4.5 x4 >= 9 This problem was solved as an LP by relaxing the restriction that all variables must be binary (i.e., the variables were allowed to take on fractional values). The optimal objective value turned out to be 10, with the optimal value for x3 being 0.5. The root node of this problem was branched on x3. The left child (corresponding to x3=0) was called CL, and its sibling was called CR. Which of these statements is true? S1: If there is any solution to this problem, then it must be at CL or at one of its descendant nodes. S2: For this integer programming problem, the optimal objective value cannot be more than 10.
