can anyone please help me understand the following two issues?
- Why do I get non-uniform and inordinate spacing between the columns? The first summation is very close to "min" and the second summation is way too from the first summation.
- Is there any way to left-align the columns? I want the third columns to be aligned left.
\documentclass[11 pt]{article} \usepackage {amsmath} \begin{document} \begin{subequations} \begin{align} \min\limits_{\lambda} & \sum\limits_{k \in R} & (\sum\limits_{i=1}^{M} a_i \quad +\\ & & \sum \limits_{j=1}^N b_j \quad + \quad \sum \limits_{j=1}^N c_j \quad + \\ \end{align} \end{subequations} \end{document}
Thanks,
P
