TLDR
This paper has developed a new algorithm for solving two counterfeit coins problem in linear time, where n is the total number of coins given and this is the first algorithm that identifies and solves the problem, given the false coins with type ω(ΔH) = ω (ΔL).
Abstract
Counterfeit coin problem is of utmost importance and it is truly interesting in Computer Science and Game theory as well as in Mathematics In this problem the objective is to detect the fake coin(s) of identical appearance but of different weight in minimum number of comparisons The word counterfeit is most frequently applicable to forgeries of currency or documents, but can also describe software, pharmaceuticals, clothing, and more recently, motorcycles and other vehicles, especially when these result in patent or trademark infringement In this paper we have developed a new algorithm for solving two counterfeit coins problem in linear time, where n is the total number of coins given However, this is the first algorithm that identifies and solves the problem, given the false coins with type ω(ΔH) = ω(ΔL), ie, one false coin is heavier and another is lighter than a true coin, and their difference in weight from the true coin is equal However, this is the degenerate case in the field of two counterfeit coins problem

Anomaly Detection and Three Anomalous Coins Problem

TL;DR: Representing coins as any data items, an algorithm to determine three false coins out of n given coins is introduced and the objective is to solve the problem in minimum number of comparisons with the help of an equal arm balance.

A generalized algorithm for solving n coins problem

TL;DR: Algorithms for solving the counterfeit coin problem for any given number n of coins are developed, based on the existing classical solution for the eight coins problem (with slight modification) for larger values of n, where n is a power of two beyond eight, as two and four being base cases.
