Narrow Gauge and Analytical Branching Strategies for Mixed Integer Programming [PDF]
arXiv, 2015 State-of-the-art branch and bound algorithms for mixed integer programming make use of special methods for making branching decisions. Strategies that have gained prominence include modern variants of so-called strong branching (Applegate, et al.,1995) and reliability branching (Achterberg, Koch and Martin, 2005; Hendel, 2015), which select variables ...

On the Age Calibration of Open Clusters Using Red Clump Stars
The Astronomical JournalIn this study, we extend the dust-independent Hatzidimitriou relation between cluster age and d _B _− _R color difference between the red giant branch (RGB) and red clump to younger cluster ages.

EPJ Web of Conferences, 2015 Clusters are excellent test benches for verification and improvement of stellar evolution theory. The recent detection of solar-like oscillations in G-K giants in the open cluster NGC6819 with Kepler provides us with independent constraints on the masses

A Comparative Study between M30 and M92: M92 is a Merger Remnant with a Large Helium Enhancement
The Astrophysical JournalWe perform a comparative study of the ex situ second-parameter pair globular clusters (GCs) M30 and M92, having similar metallicities but different horizontal branch morphologies.

Stellar Ages of TESS Stars, Adopting Spectroscopic Data from Gaia GSP-Spec
GalaxiesThe Gaia DR3 GSP-spec/TESS (GST) catalog combines asteroseismic data from NASA’s TESS mission with spectroscopic data from ESA’s Gaia mission, and contains about 116,000 Red Clump and Red Giant Branch stars, surpassing previous datasets in size and ...

Evidence of Third Dredge-up in Post-AGB Stars in Galactic Globular Clusters
The Astrophysical JournalTo better understand the mixing and mass loss experienced by low-mass stars as they ascend the asymptotic giant branch (AGB), I have gathered from the literature the abundances of CNO and s -process elements in post-AGB stars in Galactic globular ...
