### Does there exist an equivalent arithmetic circuit for each computable function?

Any computable boolean function with a fixed-length input can be computed by an arithmetic circuit. Consider any boolean function $f:\{0,1\}^n \to \{0,1\}$. Then there exists a multivariate ...

### Does every turing machine have an equivalent, single-state, n-tape turing machine?

Yes, there always exists a machine, and we really only need 2 tapes. Your standard TM transition might be written: $\delta(S_n, a) = (S_m, b, r)$ This would mean that, from $S_n$, if we read $a$, ...

### How to prove a side effect in a function

It depends on how you model the system and what proof approach you're using. For early versions of Hoare Logic, there isn't really any notion of "scope", so there's absolutely nothing special you need ...

### Solving the Path Explosion Problem in Symbolic Execution

The heuristic approach to solving the path explosion problem picks the next branch to explore based on some function. A simple heuristic function, yet pretty effective, would be to assign the score of ...

### Is it reasonable to model row buffers in DRAM corresponding to the same bank ID as one big row buffer?

You can look at how one of the existing DRAM simulators work. Consider, for example, Ramulator, which is a popular academic DRAM simulator. Ramulator Models main memory as a tree of nodes, where the ...
