Some Complexity Results for Polynomial Ideals

1997 Journal of Complexity  
We discuss further complexity results for problems related to polynomial ideals, like the word and subword problems for commutative semigroups, a quantitative version of Hilbert's Nullstellensatz in a  ...  In this paper, we survey some of our new results on the complexity of a number of problems related to polynomial ideals.  ...  We state complexity bounds as worst-case bounds in terms of the input size, which is the number of bits used to encode the input.  ...

The complexity of the word problems for commutative semigroups and polynomial ideals

Ernst W Mayr, Albert R Meyer
1982 Advances in Mathematics  
Any decision procedure for the word problems for commutative semigroups and polynomial deals inherently requires computational storage space growing exponentially with the size of the problem instance  ...  This bound is achieved by a simple procedure for the semigroup problem.  ...  Formally, a 3-counter machine C consists of a finite set Q of states, a pair of distinguished states q0 and q, E Q (where q0 is called the initial and q, the accepfing state), and a (transition) function  ...

Monte Carlo goodness-of-fit tests for degree corrected and related stochastic blockmodels [article]

Vishesh Karwa, Debdeep Pati, Sonja Petrović, Liam Solus, Nikita Alexeev, Mateja Raič, Dane Wilburne, Robert Williams, Bowei Yan
2021 arXiv   pre-print
The question of model goodness of fit, a first step in data analysis, is easy to state, but often difficult to implement in practice, particularly for large and sparse or small-sample but structured data  ...  Specifically, we construct finite-sample tests for three different variants of the stochastic blockmodel (SBM).  ...  To do this, we identify a finite collection of binomials generating the toric ideal associated to the ER-SBM.  ...

The q-theory of finite semigroups: history and mathematics [article]

Stuart W. Margolis
2014 arXiv   pre-print
This paper is a historical and mathematical review of the book, "The q-theory of Finite Semigroups" by John Rhodes and Benjamin Steinberg.  ...  Conversely, any wreath product decomposition of finite semigroups has a corresponding interpretation in terms of factorizations of finite state machines.  ...  It determined the structure of the minimal ideal of a finite semigroup and in modern terminology, the structure of finite completely simple semigroups.  ...

Computing rank of finite algebraic structures with limited nondeterminism [article]

Jeffrey Finkelstein
2020 arXiv   pre-print
In the case of groups, the previous best algorithm for computing rank used polylogarithmic space. We reduce the best upper bounds on the complexity of computing rank for groups and for quasigroups.  ...  Furthermore, if the quasigroup is a group, then the problem is also decidable by a Turing machine using O(log n) space and O(log^2 n) bits of nondeterminism with the ability to read the nondeterministic  ...  The machine M 1 accepts if and only if each of the simulations of M 2 accepts. The correctness of M 1 follows from the correctness of f and M 2 . The only remaining issue is the complexity of M 1 .  ...
