The proposed technique allows the asymptotics of the Shannon function to be established under certain structural and parametric limitations imposed on the model of binary programs.Ĭ. Ways are presented for obtaining lower and upper estimates of the Shannon function for the complexity of using Boolean functions in the class of binary programs. The functioning of this model of programs is described, as is its relationship to other discrete control systems (e.g., circuits made of functional elements or binary decision diagrams). In contrast to earleir models of binary programs, a model is introduced that admits the recursive summoning of procedures i.e., the procedures can directly summon themselves while executing a binary program, or through other procedures. The programs consist of one or several modules containing instructions of three types: computational and redirecting instructions and instructions for summoning the procedures. When the base case is reached, the function returns its value to the function by whom it is called and memory is de-allocated and the process continues.A model of binary programs implementing the functions of the algebra of logic (Boolean functions) is considered. When any function is called from main(), the memory is allocated to it on stack.Ī recursive function calls itself, the memory for called function is allocated on top of memory allocated to calling function and different copy of local variables is created for each function call. In Recursion user represent a problem in terms of one or more smaller problems, and add one or more base conditions that stop recursion.įor example, we compute factorial n if we know factorial of (n-1). Examples of such problems are Towers of Hanoi (TOH), Inorder/Preorder/Postorder Tree Traversals, DFS of Graph, etc Using recursive algorithm, certain problems can be solved quite easily. The process in which a function calls itself directly or indirectly is called recursion and the corresponding function is called as recursive function.
