Search-based Diverse Sampling from Real-world Software Product Lines [article]

Yi Xiang, Han Huang, Yuren Zhou, Sizhe Li, Chuan Luo, Qingwei Lin, Miqing Li, Xiaowei Yang
2021 Zenodo  
Real-world software product lines (SPLs) often encompass enormous valid configurations that are impossible to enumerate.  ...  To resolve this dilemma, we propose a scalable diverse sampling strategy, which uses a distance metric in combination with the novelty search algorithm to produce diverse samples in an incremental way.  ...  INTRODUCTION Software product lines (SPLs) [11] , being highly configurable, allow users to derive products by selecting and deselecting features, which are increments of product functionality.  ...

How can forest management increase biomass accumulation and CO2 sequestration? A case study on beech forests in Hesse, Germany

Joachim H. A. Krug
2019 Carbon Balance and Management  
may be explained by potentially improved resource-use efficiency.  ...  The analysis of growth-dominance structures indicates that forest management led to a situation where trees of all sizes contributed to biomass increment more proportionally; a related increase in productivity  ...  Here, management activities and intensive harvesting led to a more efficient overall stand productivity, higher increment, and biomass accumulation.  ...

Similarity-driven prioritization and sampling for product-line testing [article]

2018
Moreover, we show that applying the algorithm IncLing to sample products enhances the efficiency of product-line testing compared to existing sampling algorithms.  ...  With respect to sampling, we propose an incremental algorithm for product sampling called IncLing, which enables developers to generate samples on demand in a step-wise manner.  ...  Incremental Pairwise Sampling This chapter shares material with the GPCE'16 paper "IncLing: Efficient Product-Line Testing Using Incremental Pairwise Sampling" [Al-Hajjaji et al., 2016b] .  ...

Different patterns of selection on the nuclear genes IRBP and DMP-1 affect the efficiency but not the outcome of phylogeny estimation for didelphid marsupials

Sharon A. Jansa, Jessica F. Forsman, Robert S. Voss
2006 Molecular Phylogenetics and Evolution  
Thus, for these two genes, relaxed functional constraints and positive selection appear to improve the efficiency of phylogenetic estimation without compromising its accuracy.  ...  Using Bayesian methods, we determined that DMP1 evolves almost 30% faster than IRBP, has 2.5 times more variable sites, has less among-site rate heterogeneity, is skewed toward A and away from CT (IRBP  ...  Acknowledgments We are grateful to the curators and collections support personnel of the many museums that provided tissue samples for this work.  ...
