Abstract:There is an array of long-standing open problems in the theory of countable Borel equivalence relations (CBER), all of which state that the class of hyperfinite CBERs is nice in some way. For instance, the unresolved Union Problem asks whether the class of hyperfinite CBERs is close...
Maths, and Chemistry sections. Most of the questions were asked from the syllabus of the CBSE Class 11th and 12th curriculum. Some of the questions were based on concepts and theory. Around 27 questions seemed to be easy, 48 were moderate, and ...
The JEE Main Paper 2018 Chemistry component had a moderate to easy difficulty curve. There were questions based on both theory and formulae. There were 14 questions from the Class 12th syllabus and 16 questions from the Class 11th syllabus. This part also had 3 difficult, 17 moderate, and 1...

their simplicity and fast computation, despite the lack of guarantee that the selection is optimal with respect to the class discrimination. In wrapper methods [26–28] the relevance of a feature subset is determined according to prediction performance of the learning algorithm itself, though ...
