    • ( 4 ) The time complexity of binary search in best, worst cases for the array of size N is

    • 1) N, N2
    • 2) N, N
    • 3) 1, logN
    • 4) 1, NlogN
    • Discussion in forum
      Answer : 3) 1, logN
      Solution : In best case if the required element is at the middle then it takes O( 1 ) time other wise it takes O( log n ) time in worst case.

    • 2) OBST
    • 3) N-Queens
    • 4) 15-Puzzle
    • Discussion in forum
      Answer : 1) Bin-packing
      Solution : This one belongs to NP-Class category.

      Answer : 1) Bin-packing

    • ( 7 ) Let G be a graph with 'n' nodes and let 'm' be the chromatic number of the graph. Then the time taken by the backtracking algorithm to color it is

    • 1) O(nm)
    • 2) O(n+m)
    • 3) O(mnm)
    • 4) O(nmn).
    • Discussion in forum
      Answer : 4) O(nmn).
      Solution : As the number of internal nodes in the state space tree are mn, and O(mn) is the time spent by the NextValue algorithm to determine the children corresponding to legal colorings. Hence the total time is bounded by O(nmn).








      discussion


      Answer : 4) O(nmn).

    • ( 9 ) What would be the cost value for any answering node of a sub tree with root 'r' using branch-bound algorithm?

    • 1) Maximum
    • 2) Minimum
    • 3) Optimal
    • 4) Average
    • Discussion in forum
      Answer : 2) Minimum
      Solution : Because the objective in branch-bound algorithms is to minimize the objective function
