One-Dimensional Quantum Walks with a Position-Dependent Coin [PDF]
, 2019 We investigate the evolution of a discrete-time one-dimensional quantum walk driven by a position-dependent coin. The rotation angle which depends upon the position of a quantum particle parameterizes the coin operator. For different values of the rotation angle, we observe that such a coin leads to a variety of probability distributions, e.g ...

ESTETIKA VISUAL DAN NONVISUALKOIN CINA KUNO ASLI YANG DITEMUKAN DI BALI DAN KOIN CINA BUATAN LOKAL
Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya, 2011 Up to now, Balinese culture and art cannot be separated from the utiliza- tion of old Chinese coins which local people in Bali call pis bolong. The use of those old Chinese coins in traditional ritual in Bali is found even from the infants until the end ...

Dynamics and Probability in the Toss of a Coin with Symmetric Inhomogeneous Density [PDF]
arXiv, 2023 Under investigation in this paper is the dynamics and probability of heads in the toss of a coin with symmetric inhomogeneous density. Such coins are assumed to have diagonal inertia matrix. The rotational motion of the coin is determined by the initial angular momentum and initial position of the coin.

Optimal non-adaptive solutions for the counterfeit coin problem [PDF]
arXiv, 2015 We give optimal solutions to all versions of the popular counterfeit coin problem obtained by varying whether (i) we know if the counterfeit coin is heavier or lighter than the genuine ones, (ii) we know if the counterfeit coin exists, (iii) we have access to additional genuine coins, and (iv) we need to determine if the counterfeit coin is heavier or ...

Canonical Coin Systems for Change-Making Problems [PDF]
arXiv, 2008 The Change-Making Problem is to represent a given value with the fewest coins under a given coin system. As a variation of the knapsack problem, it is known to be NP-hard. Nevertheless, in most real money systems, the greedy algorithm yields optimal solutions. In this paper, we study what type of coin systems that guarantee the optimality of the greedy

Coins of Three Different Weights [PDF]
arXiv, 2014 We discuss several coin-weighing problems in which coins are known to be of three different weights and only a balance scale can be used. We start with the task of sorting coins when the pans of the scale can fit only one coin. We prove that the optimal number of weighings for $n$ coins is $\lceil 3n/2\rceil -2$.

Exploration with Limited Memory: Streaming Algorithms for Coin Tossing, Noisy Comparisons, and Multi-Armed Bandits [PDF]
arXiv, 2020 Consider the following abstract coin tossing problem: Given a set of $n$ coins with unknown biases, find the most biased coin using a minimal number of coin tosses. This is a common abstraction of various exploration problems in theoretical computer science and machine learning and has been studied extensively over the years.
