Special Issue Information

Dear Colleagues,

MDPI’s Information journal is introducing a new Special Issue entitled “Optimization Algorithms and Their Applications”. Original papers related to optimization algorithms and their applications will be considered for publication. This Special Issue aims to bring together researchers in the optimization algorithms and combinatorial optimization research communities to present innovative research results or novel applications. In this Special Issue, we solicit papers on various aspects of optimization algorithms from various fields such as artificial intelligence, machine learning, computer science, graphs, and novel applications of optimization on scheduling, timetabling, transportation and logistics, robotic path planning, and others to promote research activities in these fields.

Optimization problems are ubiquitous, manifesting themselves in various settings, affecting organizations (e.g., hospitals, schools, and universities), companies (e.g., transport companies, call centers, and service industries), and society at large (e.g., resource capacity planning). In this Special Issue, we welcome you to present your findings regarding the latest advances in complex optimization problems. Papers may present optimization algorithms, feature applications, novel approaches, innovative techniques, and theoretical findings on difficult optimization problems. Since such problems are computationally hard, high-performance computing approaches are welcomed and endorsed.

We welcome you to submit your most recent work in the fields of optimization algorithms, scheduling, timetabling, and their applications to this Special Issue, "Optimization Algorithms and Their Applications", in Information. Researchers from both industry and academia are warmly invited to submit either theoretical or practical research.

Dr. Christos Gogos

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Information is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Given a social network modelled by a graph, the goal of the influence maximization problem is to find k vertices that maximize the number of active vertices through a process of diffusion. For this diffusion, the linear threshold model is considered. A new [...] Read more.
Given a social network modelled by a graph, the goal of the influence maximization problem is to find k vertices that maximize the number of active vertices through a process of diffusion. For this diffusion, the linear threshold model is considered. A new algorithm, called ClusterGreedy, is proposed to solve the influence maximization problem. The ClusterGreedy algorithm creates a partition of the original set of nodes into small subsets (the clusters), applies the SimpleGreedy algorithm to the subgraphs induced by each subset of nodes, and obtains the seed set from a combination of the seed set of each cluster by solving an integer linear program. This algorithm is further improved by exploring the submodularity property of the diffusion function. Experimental results show that the ClusterGreedy algorithm provides, on average, higher influence spread and lower running times than the SimpleGreedy algorithm on Watts–Strogatz random graphs.
