This paper reports on the fourth version of the Mixed Integer Programming Library. Since MIPLIB is to provide a concise set of challenging problems, it became necessary to purge instances that became too easy. We present an overview of the 27 new problems and statistical data for all 60 instances.

We present a self-valuing learning technique which is ca-pable of learning how to grasp unfamiliar objects andgeneralize the learned abilities. The learning system con-sists of two components which distinguish between localand global quality criteria for grasp points. The localcriteria are not object-specific while the global criteriacover physical properties of each obj...

This study explored the differences in effects of collective intelligence and references on open innovation between closed access journals. analyzed moderating effect motivation from 2003 to 2006 2013 2016, considered be digital transformation era. The Scopus database journals was used for ordinary regression analysis. During 2003–2006 period, only papers demonstrated sufficient reference effec...

The MURCS association which stands for Mullerian, Renal, Cervicothoracic Somite Abnormalities is a rare developmental anomaly seen in females. The clinical course of this disorder is not clearly defined as of yet-which may range from asymptomatic to severe disability. Here we present the case of a young 22-year-old female who was incidentally detected to have a generalized increase in bone dens...

The objectives of this study were to assess the genotype (G) by environment (E) interaction of grain yield of durum wheat(Triticum durum Desf.) based on parametric models, additive main effects and multiplicative interaction (AMMI) and joint linear regression models; and compare the relative efficiency of the two models in explaining the GE effects. Twenty-three genotypes were evaluated across ...
