Definition 3. A basic feasible solution is degenerate if there are more than n tight constraints. We say that a linear programming problem is degenerate if it
has feasible solutions. But none of them is optimal (See Exercise 9.3). As a matter of fact for every number M

4 mars 2019 on the most relevant feasible solutions and an infeasible local search ... n is the number of vertices of G. Notice that a feasible solution.
Theorem 3 A balanced transportation problem always has a basic feasible solution. Such a solution consists of m + n ? 1 positive variables at most.

for any µ > 0 where P? is a feasible solution of (12.1) achieving the optimal value opt?. That is
Some simple methods to obtain the initial basic feasible solution are. 1. North-West Corner Rule. 2. Lowest Cost Entry Method (Matrix Minima Method).
Assume an LP in the following form Maximize cTx Subject to: Ax ? b x ? 0 • N Variables M constraints • U = Set of all feasible solutions
We need to introduce artificial variables to help get an initial feasible solution We also negate the objective function and convert to a maximization problem
Due to the fundamental theorem of Linear Programming to solve any LP it 'suffices' to consider the vertices (finitely many) of the polyhedron P of the feasible
THEOREM: For a feasible linear program in its standard form the optimum value of the objective over its nonempty feasible region is (a) either unbounded or
Recall the definition of a basic feasible solution: Definition 1 Let P be a polyhedron defined by linear equality and inequality constraints and consider
