Could you help me solve the problem in MathCAD? The program reports an error, but I can't understand what exactly it is.

I am trying to solve a system of equations with 90 equations in mathematica: https://www.wolframcloud.com/obj/484bbb56-7b5e-4278-8730-902844c8ccdd
Mathematica just refuses to run it after a while and it crashes. Does anyone have any tips or solutions for going around this problem?
Thank you!
I implemented an MIP optimization in CPLEX.
When I run the model, CPLEX does not show any errors and executes everything properly.
But it stops on its own within the minimization part after seconds without solution.
The solution for all my decision variables says: "No Value".
What could that mean?
Thanks a lot!
this could mean your model is not feasible.
If you name your constraints, you could get some relaxation and conflicts.

I've been attempting to check my work with Mathematica, and it's giving me the incorrect answer for a reasonably simple derivative. It also gave me the wrong solution for a different problem. I've included a screenshot of the work by hand and a screenshot of the incorrect answer.
What could be causing this error?
The Image shows a picture of the incorrect answer for a derivative
This is the solution worked out by hand.
I am trying to figure out how many primitive operations there are in this code and how many primitive operations are being executed over the runtime of this algorithm:
What have I tried to get the answer so far
I attempted to write the code out onto a piece of paper and go through it line by line. I separated each line into a cost and times ran section in hopes of figuring it out. I ended with T(O) = 2n +6i which seems incorrect.
Here is a snippet of my work:
I would greatly appreciate if someone could help me break this problem into concrete steps so I can better understand this topic as a whole.
I am a newbie to prolog and started learning prolog.
I found the missionaries and cannibals puzzle interesting to solve in prolog. I have researched a lot of forums and found the link which I think is a very good solution. But some how I am not getting the actual result. The moves on the output seem to be wrong. I tried to trace the program, everything seems perfect during the assignment of the values but somehow the solution is wrong.
I need experts help to know where exactly is the logical error.

As we discussed in the comments of the post, there was no logical error, just an ill chosen output format.
