![]() ![]() For the purpose, we show that CRM is related to the method of subgradient projections. We prove local convergence of CRM in the same prototypical settings of most theoretical analysis of regular nonconvex DR, whose consideration is made natural by the geometry of the phase retrieval problem. It is closely related with Douglas–Rachford method (DR). ![]() Recently, circumcentering reflection method (CRM) has been introduced for solving the feasibility problem of finding a point in the intersection of closed constraint sets. The experimental results show that the proposed EDDA algorithm can solve the four-color map problem with more than 100 regions. Finally, six real-life maps are colored to verify the effectiveness of the proposed algorithm. ![]() A greedy strategy, local differential cross strategy, and single-point switching strategy are then used to solve the problem of conflicts among adjacent nodes. We use global and local discrete alternate search strategies-when there is at least one adjacent dragonfly around the i-th dragonfly, a global search is performed when there are no other dragonflies around, a local search is performed. This article proposes an enhanced discrete dragonfly algorithm (EDDA) for four-color map problems. There have been many applications of swarm intelligence optimization algorithms to this problem, but to date, such algorithms can only solve the four-color map problem with fewer than 100 regions. One example of the graph coloring problem is the four-color map problem. The classic combinatorial optimization problem of graph coloring is one of the most famous NP-complete problems. Linear convergence Mathematics Subject Classification 47H05.Relaxed splitting method with linearization.The general splitting method with linearization.The numerical examples are presented to illustrate the advantage of our methods by comparing with other methods. ![]() The weak convergence of two proposed methods is established under standard conditions and the linear convergence of the general splitting method with linearization is analyzed. These ways of selecting stepsizes and relaxation parameters are also practised to the relaxed splitting method with linearization where the two closed convex sets are both level sets of convex functions. We present the constant and adaptive relaxation parameters, and the latter is "optimal" in theory. In this article, we introduce a general splitting method with linearization to solve the split feasibility problem and propose a way of selecting the stepsizes such that the implementation of the method does not need any prior information about the operator norm. Our Reduced Quantum Genetic Algorithm (RQGA) circuit implementation and the graph coloring results show that quantum heuristics can tackle complex computational problems more efficiently than their conventional counterparts. We examine the results, analyze the algorithm convergence, and measure the algorithm's performance using the Qiskit simulation environment. , the minimum number of colors required to color the graph). The proposed implementation solves both vertex and edge coloring and can also determine the chromatic number ( i.e. This paper proposes an instantiation of the Reduced Quantum Genetic Algorithm (RQGA) that solves the NP-hard graph coloring problem in O(N 1/2 ). Because we can simulate the quantum circuits that implement GA in different highly configurable noise models and even run GA on actual quantum computers, we can analyze this class of heuristic methods in the quantum context for NP-hard problems. Genetic algorithms (GA) are computational methods for solving optimization problems inspired by natural selection. ![]()
