Only thing I was unable to do on my own when following your video was to find the "Limits Report" which didn't show up anywhere in my Excel document. I'm using the newest versions of things, so it probably is just somewhere I don't know where to look for it

Interesting. ... going to school in the early 70s, we did all of this by hand... with the use of a slide rule to estimate the answer and then draw a couple of graphs by hand to zero in on the better answer. Them were the days!! Enjoyed the clip.

Back in the days, we used simplex method, and I wrote C program to solve the opimization... now there is an excel solver.... People have forgotten the importance of solving problems on their own.

@MattMacarty

4 жыл бұрын

Agreed If I were in a classroom I would have started by solving with Simplex and then moved onto Solver. Most courses still cover with a graphical example so you can see what's going on but as soon as you move past a couple of variables pretty much everyone is using a solver. I was actually considering showing Simplex with a python program but I haven't gotten to it yet.

Hi. I have a question. I created a macro (VBA) that emulates the solver by clicking on a button. The problem is that sometime I have to click 3-4 times before getting the last results. Do you know how to avoid this and getting on solution with one click?

@MattMacarty

5 жыл бұрын

Hi. This is really difficult to diagnose, but one thing to consider is that usually there are many feasible solutions, but only one optimal solution. it sounds like maybe your script is stopping once it finds a feasible solution and then on subsequent runs it gets closer and closer to the optimal. Another common problem is in the modeling step. It's pretty easy to design your model in such a way that it is no longer linear. When this happens you sometimes end up with "local" optima rather than global optima.

My professor literally gave us a link to this video instead of just teaching it himself, I wish I can just take back the money I gave to my professor and give it to you instead. Have my like and sub cuz idk how else to repay u back
