We study a disturbed variant of the classical greedy algorithm for weight functions defined on some given finite set E and show that the greedy algorithm for matroids is stable with respect to changes in the input data.

The concept of a combinatorial W P U -geometry for a Coxeter group W , a subset P of its generating involutions and a subgroup U of W with P ⊆ U yields the combinatorial foundation for a unified treatment of the representation theories of matroids and of even -matroids. The concept of a W P -matroid
