A stack of code is not the same as a stack of programs, Harvard computer science professor says
A stack is a collection of programs.
Stack programming is not a stack, says Harvard computer scientist David Minsky, and it is not an algorithm.
“I would like to suggest that there is a fundamental difference between a stack and a stack program,” Minsky told me in an interview.
Minsky has a strong track record of using stacks in research and his papers show he has developed and tested some very useful algorithms and data structures.
But he has also used stacks for programming.
“Stack programming is like a recursive function, and you can use stack programming to do recursive functions,” Minky said.
“You can use a stack to do the recursive function or you can do a stack as an iterative function, in which you do a bunch of recursive functions.”
He said that he used stacks as an example of how to use algorithms in programming.
The Stack as an Iterative Function The stack as a function can be written in a recursive fashion, like this: a function that takes a stack (the stack of stack values) and returns a stack value.
Minky first introduced stack programming in a computer science paper, “A Stack as An Iterative Variable,” published in 2008.
Minks work has focused on stacks because he thinks that stacks can be used to represent algorithms.
Mink’s paper focused on an algorithm called the algorithm for determining the position of an object within a grid of numbers.
It can be implemented as a program that takes an arbitrary sequence of numbers and returns an arbitrary value.
Stack Programming as an Example of a Recursive Function A stack can also be written as an iterator function.
A stack, in this example, takes a list of numbers as input and a list as output.
The stack can then be iterated over to find the values that the algorithm finds the position for.
The algorithm for finding the position can then repeat this process until it reaches a position that satisfies the condition.
Stack programs can be found online and have been used to solve problems that require a recursive algorithm in computer science classes.
Minski uses stacks to implement recursive functions in his research and in a book he co-authored with the late David Pincus, “Recursive Programming.”
Stack Programming and Recursive Algorithms As with all of the algorithms in Minsky’s work, a stack is implemented as an algorithm that uses a stack.
Minki first showed how to implement a recursive implementation of the algorithm, “Stack Recursive Functions,” in his 2008 paper, where he wrote: A recursive function is a function whose return value satisfies a condition and whose return values are all equal.
For example, suppose we want to calculate the position in a grid where we have a large number of points.
This function can take as input a sequence of integers, which are a list, and as output a list that can hold a list containing integers.
Here is how the function should look: a list [n] :: Int n => [Int] -> Int a list = [x,y,z,n] where x = n + 1 y = n – 1 z = n / 2 n / [1,2,3] z = x / (n-1) m = [2,4,5] m = m / (1+m) where xs = m * (n+1) ys = n * (1-m) zs = z * (m-1)/ (1) Here are the functions that Minsky and Pincuss implemented: function m_sum (s,n,i) return m(n+i,n) function m(x, y,z) return x + y + z function mx_sum(x1,y1,z1) return (mx(x-1),mx1(y-1)) function mz_sum((x1-x2),y1-y2) return ((mx0(x2-x1), mx1(-1)),mx2(y2)) function Mx_msum(m,n){ return m/(n+n-m-m1)*(m+n)-m1*(m2-m2) } function m[i,j]=(m+j)*(n-i)*(i-j) return Mx[m[i],[m[j]]] function m+=(n-j)*((m+i)-m-i) where mx = i-1 mx=i-1 i=0 m+ = m/ mx return m return M Minsky wrote a few more papers on stack programming and recursive algorithms.
In one paper he showed how stack programs could be used for other tasks.
For instance, Minsky showed that it was possible to use stacks to solve algorithms for detecting and solving the differential equation problem.
