Approximation algorithms | Reduction (complexity)
In computer science, particularly the study of approximation algorithms, an L-reduction ("linear reduction") is a transformation of optimization problems which linearly preserves approximability features; it is one type of approximation-preserving reduction. L-reductions in studies of approximability of optimization problems play a similar role to that of polynomial reductions in the studies of computational complexity of decision problems. The term L reduction is sometimes used to refer to log-space reductions, by analogy with the complexity class L, but this is a different concept. (Wikipedia).
Understanding Limits and L'Hospital's Rule
We learned about limits earlier in this series. We know what they represent, and we know how to evaluate them. Then we found that we don't need them that much, because we have better methods for differentiating functions than all that business with tangent lines and limits. But limits stil

Separating Components of a Mixture by Extraction
When we perform a chemical reaction, we are usually trying to get a particular molecule. But when we are done with the reaction, there will probably be a bunch of different stuff in the reaction flask. How do we get just the thing we want and not the other stuff? It's actually pretty invol

This is different from the redox we knew from general chemistry. It's not so much about highlighting electron transfer as it is about the number of bonds to oxygen that an atom possesses. An oxidation increases a carbon's bonds to oxygen, a reduction reduces a carbon's bonds to oxygen. Mak

Reduction of Esters With DIBAL-H
We know about a lot of different oxidizing and reducing agents that facilitate a variety of different transformations. But we haven't touched upon the precise transformation that can be achieved by diisobutylaluminum hydride, also known as DIBAL-H. Let's see what this does and why it is so

Initial Theta Data - part 02 - Transvections
In order to state the "technical part" of initial theta data we need to talk about bases of the l-torsion under the Tate uniformization. This can be found in Silverman's - Advanced Topics - Chapter V, section 6.
