Linear programming 1 Basics - MIT Mathematics
Linear programming Lecturer: Michel Goemans 1 Basics Linear Programming deals with the problem of optimizing a linear objective function subject to linear equality and inequality constraints on the decision variables. Linear programming has many practical applications (in transportation, production planning, ...). It is also the building block for

V7. Laplace’s Equation and Harmonic Functions
math.mit.eduA. Existence. Does there exist a φ(x,y) harmonic in some region containing Cand its interior R, and taking on the prescribed boundary values? B. Uniqueness. If it exists, is there only one such φ(x,y)? C. Solving. If there is a unique φ(x,y), determine it by some explicit formula, or approximate it by some numerical method.
The Limit of a Sequence - MIT Mathematics
