    I am having some problems with some D1 questions:

    1: On dijkstra some questions say find the shortest route excluding a specific arc, including a specific vertex etc, how do I do these?
    2: How do you do gantt charts and scheduling diagrams quickly and how do you draw scheduling diagrams without a gantt chart?
    3: How do you determine how many workers from a gantt chart?
    4: What do you do on the route inspection questions where they remove an arc (June 2012)
    5: What is the maximum number of passes to complete an n list bubble sort?
