• Location: Location science deals with the location of one or more facilities in a way that optimizes a certain objective, such as minimizing transportation cost, minimizing the undesirable effects produced by the facility, capturing the largest market share, etc. Location of hospitals, supermarkets, petrol-stations, warehouses, nuclear plants or radar beams are some examples. Location models differ one another from the space where the facility is to be located (a subset of the plane or of some n-dimensional space, a network, a discrete set, ...), the number of new facilities to be located, the number of existing facilities, the decision maker's objective and the customers. The more realistic the problem is, the more difficult to find its solution becomes.

Many other fields have direct connections with location science, either by subject or as techniques used in the design of algorithms, such as transportation and routing problems, mathematical (linear, integer, nonlinear, convex, global, ...) programming, multicriteria analysis, approximation theory, computational geometry, ...

• Global Optimization: One of the most important problems in Mathematics is the one of optimizing a given function f(x), x in Rⁿ, subject to some constraints, g(x)=0, h(x)<=0, where g is a m-vectorial function and h a r-vectorial function. If (a) the objective function f is convex and (b) the feasible set defined by the points satisfying the constraints is convex, then there are efficient algorithms which can solve the problem. They are based of the fact that a local optimum is also a global optimum.

Nevertheless, if one (or both) of those conditions does not hold, the problem is much more difficult to solve, since there may exist local optima that are not global. All standard techniques in nonlinear optimization can at most locate local optimal points, and there is no local criterion for deciding whether a local solution is global. Therefore, conventional methods of optimization using such tools as derivatives, gradients, subgradients and the like, are, in general, not capable of locating or identifying a global optimum.

Due to those difficulties, the methods devised for solving global optimization problems are significantly different from the standard tools referred above. In order to build a numerically promising implementation, additional properties of the problem's data usually have to be exploited.

The following book is an excellent introduction to the area:

• Horst R. and Tuy H. (1996):  "Global optimization. Deterministic approaches (3rd edition)", Springer-Verlag, Berlin.

• Interval Analysis: Traditionally, a computer can only obtain approximate solutions to a given problem. Even though approximations are often satisfactory, they may nevertheless be inaccurate or even completely wrong. Some disasters attributable to bad numerical computing (the Patriot Missile failure, in Dharan, Saudi Arabia, on February 25, 1991 which resulted in 28 deaths; the explosion of the Ariane 5 rocket just after lift-off on its maiden voyage off French Guiana, on June 4, 1996; and the sinking of the Sleipner A offshore platform in Gandsfjorden near Stavanger, Norway, on August 23, 1991) can be seen at https://www.iro.umontreal.ca/~mignotte/IFT2425/Disasters.html

Interval Analysis is a field of numerical analysis where the basic elements of the calculations are intervals of real numbers. With the use of directed rounding, we can automatically encapsulate the true solution in intervals. Interval Analysis allows to create algorithms which use set theoretic existence theorems; in this way, not only it is possible to design interval algorithms able to solve difficult problems but also they are able to prove the existence and uniqueness of the theoretic solutions that they compute enclosures of (these algorithms are called "Self Validating Algorithms").

Interval Analysis has been applied to different problems, such as: linear and nonlinear systems, global optimization, constraint propagation, fuzzy logic, economic input-output models, quality control in manufacturing design, quantum mechanics, medical expert systems and others.
