We consider representing of natural numbers by expressions using 1's, addition, multiplication and parentheses. $\left\| n \right\|$ denotes the minimum number of 1's in the expressions representing $n$. The logarithmic complexity $\left\| n \right\|_{\log}$ is defined as $\left\| n \right\|/{\log_3 n}$. The values of $\left\| n \right\|_{\log}$ are located in the segment $[3, 4.755]$, but almost nothing is known with certainty about the structure of this "spectrum" (are the values dense… 

Integer Complexity: Algorithms and Computational Results

An algorithm for computing K(n) is described, and it is shown that the set of stable numbers is a computable set, and the defect of a number is defined by $\delta(n):=\|n\|-3\log_3 n$, building on the methods presented in [3].

Algorithms for determining integer complexity

Three algorithms to compute the complexity of all natural numbers, each superior to the one in [11], are presented and it is shown that they run in time $O(N^\alpha)$ and space $N\log\log N)$.

An Application of Markov Chain Analysis to Integer Complexity

Markov chain methods are used to analyze a large class of algorithms, including one found by David Bevan that improves the upper bound to f(n) \leq 3.52 \log_{3}{n}$$ on a set of logarithmic density one.

On Algorithms to Calculate Integer Complexity

A method is discussed that provides a strong uniform bound on the number of summands that must be calculated for almost all $n$ and potential improvements to this algorithm are discussed.

Digits of pi: limits to the seeming randomness

The decimal digits of $\pi$ are widely believed to behave like as statistically independent random variables taking the values $0, 1, 2, 3, 4, 5$, $6, 7, 8, 9$ with equal probabilities $1/10$. In

Upper Bounds on Integer Complexity

This paper provides the first non-trivial upper bound for all n, where for all $n>1$ the authors have $||n|| \leq A \log n$ where $A = \frac{41}{\log 55296}$.

Optimal Presentations of Mathematical Objects

We discuss the optimal presentations of mathematical objects under well defined symbol libraries. We shall examine what light our chosen symbol libraries and syntax shed upon the objects they

Some Conceptual and Measurement Aspects of Complexity, Chaos, and Randomness from Mathematical Point of View

This study aims to reveal and emphasize the role of mathematics in formulating the conceptual and measurement stages of complexity, chaos, and randomness in natural dynamical systems.

Integer Complexity and Well-Ordering

Define $\|n\|$ to be the complexity of $n$, the smallest number of ones needed to write $n$ using an arbitrary combination of addition and multiplication. John Selfridge showed that $\|n\| \ge

Integer Complexity: Experimental and Analytical Results

We consider representing of natural numbers by arithmetical expressions using ones, addition, multiplication and parentheses. The (integer) complexity of n -- denoted by ||n|| -- is defined as the

Integer Complexity, Addition Chains, and Well-Ordering.

Two notions of the “complexity” of a natural number are considered, the first being addition chain length, and the second known simply as “integer complexity”, which is the smallest number of 1’s needed to write n using an arbitrary combination of addition and multiplication.

"How many $1$'s are needed?" revisited

We present a rigorous and relatively fast method for the computation of the "complexity" of a natural number (sequence A005245), and answer some "old and new" questions related to the question in the

On the representation of an integer in two different bases.

In 1970 Senge and Strauss [4] proved that the number of integers, the sum of whose digits in each of the bases a and b lies below a fixed bound, is fmite if and only log if is irrational. Their

Numbers with Integer Complexity Close to the Lower Bound

This paper presents a method for classifying all n with for a given r, and proves that for with m and k not both zero, and present a method that can, with more computation, potentially prove the same for larger m.

Maximal Independent Sets and Separating Covers

A combinatorial explanation for this relationship, via Moon and Moser's answer to a question of Erdős: how many maximal independent sets can a graph on n vertices have, is given.

The On-Line Encyclopedia of Integer Sequences (or OEIS) is a database of some 130000 number sequences which serves as a dictionary, to tell the user what is known about a particular sequence and is widely used.

A short note on integer complexity

This short note gives a new, constructive upper bound on the smallest number of 1's needed in conjunction with arbitrarily many +, *, and parentheses to write an integer n for generic integers n.

Automatic Sequences - Theory, Applications, Generalizations

This chapter discusses automata, automatic sequences, and other models of computation in number theory and algebra, as well as number systems and numeration systems, and some examples of these models are presented.
