Unique Application

Using complete enumeration (e.g., generating all possible subsets of item combinations) to evaluate clustering problems has the benefit of locating globally optimal solutions automatically without the concern of sampling variability. The proposed method is meant to combine clustering variables in such a way as to create groups that are maximally different on a theoretically sound derivation variable(s). After the population of all unique sets is permuted, optimization on some predefined, user-specific function can occur. We apply this technique to optimizing the diagnosis of Alcohol Use Disorder. This is a unique application, from a clustering point of view, in that the decision rule for clustering observations into the diagnosis group relies on both the set of items being considered and a predefined threshold on the number of items required to be endorsed for the diagnosis to occur. In optimizing diagnostic rules, criteria set sizes can be reduced without a loss of significant information when compared to current and proposed, alternative, diagnostic schemes.

New Directions

Research has demonstrated that psychiatric diagnoses bear no relationship to certain important psychological variables, e.g., broad personality characteristics or even such clinically important issues as aetiology or prognosis (Frank, 1975). From that research, one dimension emerged which did yield information regarding aetiology and prognosis, viz., the process-reactive differentiation. As it seems important to examine this differentiation from a personological point of view, this review focused on the Rorschach performance of process and reactive schizophrenics. Essentially, the Rorschach studies suggest that process schizophrenics manifest more serious psychopathology cognitively than do reactives. Suggestions for further research were made.

Abstract The paper on hand approaches the classical makespan minimization problem on identical parallel machines from a rather theoretical point of view. Using an approach similar to the idea behind inverse optimization, we identify a general structural pattern of optimal multiprocessor schedules. We also show how to derive new dominance rules from the characteristics of optimal solutions. Results of our computational study attest to the efficacy of the new rules. They are particularly useful in limiting the search space when each machine processes only a few jobs on average.

Combinatorial Optimization Problems

The scale and complexity of search space are important factors deciding the solving difficulty of an optimization problem. The information of solution space may lead searching to optimal solutions. Based on this, an algorithm for combinatorial optimization is proposed. This algorithm makes use of the good solutions found by intelligent algorithms, contracts the search space and partitions it into one or several optimal regions by backbones of combinatorial optimization solutions. And optimization of small-scale problems is carried out in optimal regions. Statistical analysis is not necessary before or through the solving process in this algorithm, and solution information is used to estimate the landscape of search space, which enhances the speed of solving and solution quality. The algorithm breaks a new path for solving combinatorial optimization problems, and the results of experiments also testify its efficiency.

First Time

In this work we show how to use a quantum adiabatic algorithm to solve multiobjective optimization problems. For the first time, we demonstrate a theorem proving that the quantum adiabatic algorithm can find Pareto-optimal solutions in finite-time, provided some restrictions to the problem are met. A numerical example illustrates an application of the theorem to a well-known problem in multiobjective optimization. This result opens the door to solve multiobjective optimization problems using current technology based on quantum annealing.

A new metaheuristic algorithm is proposed for Capacitated Vehicle Routing Problem. CVRP is one of the fundamental problems in combinatorial optimization that deals with transport route minimization. The algorithm combines Simulated Annealing, multi-start and simultaneous computing techniques. A series of computational tests are conducted on several CVRP benchmarks and near-optimal solutions are obtained. The results indicate superior performance compared with Simulated Annealing

The article describes the role of the Internet in the modern information society. The negative consequences of the openness of this information and telecommunications network are studied. The paper also substantiates the consequences of the activities of anonymous users who commit offenses. The authors consider the experience of combating fake news in developed countries (Great Britain, Germany, France) and emerging markets (Brazil, Venezuela, Egypt, Qatar, China, Singapore, Turkey). Special attention is paid to such a new phenomenon in the field of spreading false information as "deepfakes". As a result of a comparative legal analysis of regulation in the field of countering the publication of information that does not correspond to reality in online publications, it is concluded that many countries have realized the importance of the threat of spreading fake news. Foreign legislation is formed from the point of view of creating preventive measures in the field of dissemination of unreliable socially significant information. In addition, the authors of the study noted that the adoption of legal measures to combat the spread of fake news at the national level helps to minimize the negative socially significant consequences of the activities of offenders. From this point of view, these actions are absolutely justified and have a positive impact on the regulation of public relations on the Internet.

Abstract Cable and hose routing is a complex and time-consuming process that often involves several conflicting objectives. Complexity increases further when routes of multiple components are to be considered through the same space. Extensive work has been done in the area of automatic routing where few proposals optimize multiple hoses together. This paper proposes a framework for the routing of multiple pre-formed hoses in an assembly using a unique permutation process where several alternatives for each hose are generated. A combinatorial optimization process is then used to find Pareto-optimal solutions for the multi-route assembly. This is coupled with a scoring model that predicts the overall fitness of a solution based on designs previously scored by the engineer as well as an evaluation system where the engineer can score new designs found through the use of the framework to update the scoring model. The framework is evaluated using a testcase from a car manufacturer showing a severalfold time reduction compared to a strictly manual process. Considering the time savings, the proposed framework has the potential to greatly reduce the overall routing processes of hoses and cables.
