My purpose is to write a academic paper related to shared computing more abstractly and I need to refer to these variables in both equation and its corresponding pseudocode.

In my pseudocode I have nested structs, where it makes it harder to represent them in simplified equations.


Assume I have following nested structs in C. Jobs struct uses Fees struct. Fees could have additinal stuct inside and so on.

struct Fees {
    int cpu;
    int data;
}

struct Jobs {
   struct Fees F;
   int start_time;
   int completion_time;
   int run_time;
   int requested_cpu;
}

int main( ) {
   struct Jobs j;
   j.F.cpu = 20
   j.F.data = 10

   nproc = 4
   run_time = 60
   cost = j.F.cpu * nproc * run_time
   // ... //
}

In C code, I can access/represent the variable using j.F.cpu. Could I use same way as mathematical notation? or should I do subscript for the objects' variables, such as $j.F_{cpu}$? or should I do completely different approach?

Assume $j$ is a Job object. Alternative to $j.F.cpu$, I come up following subscripts examples:

  • $j.F^{cpu}$ == $j.F^{cpu}$
  • $j.F_{cpu}$ == $j.F_{cpu}$
  • $j_{F_{cpu}}$ == $j_{F_{cpu}}$
  • $j_{F^{cpu}}$ == $j_{F^{cpu}}$
  • $j_{F.{cpu}}$ == $j_{F.{cpu}}$

Related: How can I define programming struct variables as mathematical notation?

I am using following approach if there is not nested structs:

As a stylistic matter, I don't like j.X^{t}; I would just use j.X

  • $\begingroup$ I don't see a real need to reflect the structs at all in the mathematical explanation. By the way, Fees is used only once, so needn't even exist. $\endgroup$

  • $\begingroup$ I show fee usage once for a basic example, in my real implementation it is used more than once. $\endgroup$
