Multiple choice

For the network, the objective is to find the length of the shortest path from node P to node G. Let dv be the length of directed are from node I to node j. Let sj be the length of the shortest path from P to node j. Which of the following equations can be used to find SG?

  1. SG = Min{SQ, SR}

  2. SG = Min{SQ- dQG, SR - dRG}

  3. SG = Min{SQ + dQG, SR + dRG}

  4. SG = Min{dQG, dRG}
