Complex & Intelligent Systems aims to provide a forum for presenting and discussing novel approaches, tools and techniques meant for attaining a cross-fertilization between the broad fields of complex systems, computational simulation, and intelligent analytics and visualization. The transdisciplinary research that the journal focuses on will expand the boundaries of our understanding by investigating the principles and processes that underlie many of the most profound problems facing society today. Key topics of focus include: Complexity - Complex evolutionary and adaptive Systems - Emergent properties and behavior in complex Systems - Self-organizing collective systems - Biological and social inspirations in problem solving - Systems Science and Engineering Intelligent Data Analytics - Data mining and knowledge discovery - Machine learning - Pattern recognition - Big Data Analytics and data science - Data-driven problem solving Computational Simulation - Knowledge-based Systems - Agent based Systems - Uncertainty modeling - Decision support Systems - Brain-like computing - Ubiquitous computing - Computational visualization and interaction Complex & Intelligent Systems is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct. Authors should refrain from misrepresenting research results which could damage the trust in the journal and ultimately the entire scientific endeavor. Maintaining integrity of the research and its presentation can be achieved by following the rules of good scientific practice as detailed here: https://www.springer.com/us/editorial-policies Evaluation process: After technical check and screening for English quality, all new submissions are automatically screened using CrossCheck within the editorial system to detect cases of suspected plagiarism. Editors are also able to run a similarity report at any other point during the review process or post-publication. All manuscripts are subject to a double-blind peer review process during at least 2 rounds coordinated by a Chief Editor responsible for the respective submission track (major topic). The average time from submission until the final decision is five months. The acceptance rate is around 26%. The evaluation workflow is supervised and monitored by an Editors-in-Chief. .
