How do you find the basic solution in LPP?
(1) A solution x of Ax = b is called a basic solution if the vectors {ai : xi = 0} are linearly independent. (That is, columns of A corresponding to non-zero variables xi are linearly independent.) (2) A basic solution satisfying x ? 0 is called a basic feasible solution (BFS).What is a basic solution in LLP?
In linear programming, a discipline within applied mathematics, a basic solution is any solution of a linear programming problem satisfying certain specified technical conditions.How do you identify a basic feasible solution?
A solution in P = {x : Ax ? b} is called basic feasible if it has n linearly independent active constraints. Definition 3. A solution in P = {x : Ax ? b} is called degenerate if it has more than n linearly independent active constraints.6 mar. 2014- If the column is cleared out and has only one non-zero element in it, then that variable is a basic variable. If a column is not cleared out and has more than one non-zero element in it, that variable is non-basic and the value of that variable is zero.
