Assembly theory and its relationship with computational complexity [PDF]

open access: greennpj Complexity
Assembly theory (AT) quantifies selection using the assembly equation, identifying complex objects through the assembly index, the minimal steps required to build an object from basic parts, and copy number, the observed instances of the object.

Computational Complexity Theory and the Philosophy of Mathematics† [PDF]

open access: greenPhilosophia Mathematica, 2019
AbstractComputational complexity theory is a subfield of computer science originating in computability theory and the study of algorithms for solving practical mathematical problems. Amongst its aims is classifying problems by their degree of difficulty — i.e., how hard they are to solve computationally.

Probabilistic Recursion Theory and Implicit Computational Complexity [PDF]

open access: diamondScientific Annals of Computer Science, 2014
We show that probabilistic computable functions, i.e., those func- tions outputting distributions and computed by probabilistic Turing machines, can be characterized by a natural generalization of Church and Kleene’s partial recursive functions.

Computational complexity of interacting electrons and fundamental limitations of density functional theory [PDF]

open access: bronze, 2009
Using arguments from computational complexity theory, fundamental limitations are found for how efficient it is to calculate the ground-state energy of many-electron systems using density functional theory.

Relativization of the Theory of Computational Complexity [PDF]

open access: bronzeTransactions of the American Mathematical Society, 1976
Blum''s machine-independent treatment of the complexity of partial recursive functions is extended to relative algorithms (as represented by Turing machines with oracles). We prove relativizations of several results of Blum complexity theory, such as the compression theorem.

An Overview of the Theory of Computational Complexity [PDF]

open access: yesJournal of the ACM, 1971
The purpose of this paper is to outline the theory of computational complexity which has emerged as a comprehensive theory during the last decade. This theory is concerned with the quantitative aspects of computations and its central theme is the measuring of the difficulty of computing functions.
