Combinatorial optimization | Constraint programming
In the field of mathematics called combinatorial optimization, the method of symmetry-breaking constraints can be used to take advantage of symmetries in many constraint satisfaction and optimization problems, by adding constraints that eliminate symmetries and reduce the search space size. Symmetries in a combinatorial problem increase the size of the search space and therefore, time is wasted in visiting new solutions which are symmetric to the already visited solutions. The solution time of a combinatorial problem can be reduced by adding new constraints, referred as symmetry breaking constraints, such that some of the symmetric solutions are eliminated from the search space while preserving the existence of at least one solution. Symmetry is common in many real-life combinatorial problems. For example, certain vehicles in the vehicle routing problem might be identical. For a valid routing plan, every permutation of such identical vehicles yields another valid routing plan with the same objective function value. (Wikipedia).
Computing Limits from a Graph with Infinities
In this video I do an example of computing limits from a graph with infinities.

This video covers the laws of limits and how we use them to evaluate a limit. These laws are especially handy for continuous functions. More theorems about limits are introduced in later videos. For more videos visit http://www.mysecretmathtutor.com

Today we talk about Limit Laws. We go through some very fundamental properties of limits that are required to understand how some very difficult limits are solved. Visit my website: http://bit.ly/1zBPlvm Subscribe on YouTube: http://bit.ly/1vWiRxW Hello, welcome to TheTrevTutor. I'm here

Limit of (x + 2)/(x^3 + 8) as x approaches -2
In this video we work out the limit of (x + 2)/(x^3 + 8) as x approaches -2. We do this by factoring the denominator with the sum of cubes by using the sum of cubes formula.Then we can cancel and evaluate the limit. Another way to do this problem is to use something called L'Hopital's rule

The hardest concept in Calculus? #SoME2
The ε-δ definition of limits is infamous among calculus students for being confusing to understand and cumbersome to use. In this video I show what is the geometrical interpretation of that definition and give an example of how it is actually used in practice connecting the steps of the re
