    You round down because it needs to be in the feasible region as well as being an integer - it depends on the question

    Oh okay thanks

    So I guess it's best to just check the value satisfies the inequalities for the feasible region

    Hi,
    Is there any easy way to do a scheduling diagram WITHOUT drawing a cascade diagram/gantt chart first?
    Thanks

    I tried to search for a method yesterday, and I don't think there is, the only way is trial and error which would take too long. 😭

    Just look at the numbers from the early/late event time diogram and make sure you keep dependencies in mind? That's what I do at least!

    When drawing a scheduling diagram, if we draw a Gantt chart first, should we cross it out? Or can we leave both there?

    Nodes and vertices are interchangeable; use whichever. The same goes for edges and arcs.

    Well they don't take marks away, so I don't see how giving data which helps you but is not credited would leave you in any worse situation apart from time wise. Takes along time to draw a gantt for a 3/4 scheduling which may take 3/4+ mins anyway on it's own.

    Anyone just to confirm - Prim's Algorithm is the one where you don't cross out arcs as you write them down, and Kruskal's is the one where you do? Right?

    According to Edexcel the grade boundary for an A this year is 71. I think it's something to do with them making the exams harder this year.

    Obvious lie. Grade boundaries come out inAugust and are always around the 60 mark for an A.

    When filling out an algorithm table, how do you know when to skip a row and when not to??

    From my computing knowledge:
    An algorithm table is basically a small computer program. When a value updates you just need to jot down it's current value. When the computer reads the value it only wants the most recent so there is no reason why a row would be skipped; unless for human clarity. I don't think it matters as long as it is in the right order.

    Actually if you look at the grade boundarieshttps://d0247e65b1a6ead8e6286cd43803...%20A-level.pdf)

    they have generally been in the range of 60-70 marks. There has also been reports on the edexcel webpage saying that the boundaries are increasing past this. I may still be wrong, but Edexcel are suggesting this.
