Abstract: This paper proposes a new algorithm for two-stage robust optimization problems like security-constrained transmission switching called column-and-constraint substitution. Previous methods ...

In this article, we have prepared 25 questions based on Problem solving by substitution method as it is very necessary from the point of view of questions asked in SSC exams. In this article, The ...

Substitution means putting numbers in place of letters to calculate the value of an expression. An expression can be a combination of numbers, letters and operators, grouped together.
