This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Abstract—In the precursor paper [1], a many-objective optimization method (NSGA-III), based on the NSGA-II framework, was suggested and applied to a number of unconstrained (with box constraints(More)
The objective in extreme multi-label learning is to train a classifier that can automatically tag a novel data point with the most relevant subset of labels from an extremely large label set. Embedding based approaches attempt to make training and prediction tractable by assuming that the training label matrix is low-rank and reducing the effective number(More)
Boolean satisfiability (SAT) solvers are used heavily in hardware and software verification tools for checking satisfiability of Boolean formulas. Most state-of-the-art SAT solvers are based on the Davis-Putnam-Logemann-Loveland (DPLL) algorithm and require the input formula to be in conjunctive normal form (CNF). We present a new SAT solver that operates(More)
Model checking techniques applied to large industrial circuits suffer from the state space explosion problem. A major technique to address this problem is abstraction. The most commonly used abstraction technique for hardware verification is localization reduction, which removes latches that are not relevant to the property. However, localization reduction(More)

We experimentally demonstrate the coexistence of two opposite photo-effects, viz. fast photodarkening (PD) and slow photobleaching (PB) in Ge(19)As(21)Se(60) thin films, when illuminated with a laser of wavelength 671 nm. PD appears to begin instantaneously upon light illumination and saturates in tens of seconds. By comparison, PB is a slower process that(More)
The primary motivations for the formation of airline alliances have been to increase revenues and decrease costs for alliance partners. A major advantage comes through increase in the number of destinations served by an airline at little costs, by using codesharing. Airlines share seat inventory on each other's codeshare flights which complicates their(More)
Checking the equivalence of a system-level model against an RTL design is a major challenge. The reason is that usually the system-level model is written by a system architect, whereas the RTL implementation is created by a hardware designer. This approach leads to two models that are significantly different. Checking the equivalence of real-life designs(More)
