Popis: It is well known that for any partitioning of the variables of a linear program, optimal aggregation weights exist. In the present paper we show that if two or more of the optimal basic variables of the original problem are aggregated into the same variable using optimal weights, the optimal solution of the aggregated problem is degenerate.
