Coupled placement of items using stable marriage techniques

A computer program embodied on a computer readable medium, comprising:

• program instructions for ranking a first resource node group for each first element of a plurality of coupled items, each of the plurality of coupled items having a first element and a second element;
• program instructions for determining placement of each first element of the plurality of coupled items on one first resource node of the first resource node group by iteratively comparing in order of ranking a first profit value associated with each placement and placing the first element having a highest first profit value;
• program instructions for ranking a second resource node group for each second element of the plurality of coupled items;
• and
• program instructions for determining placement of each second element of the plurality of coupled items on one second resource node of the second resource node group by iteratively comparing in order of ranking a second profit value associated with each placement and placing the second element having a highest second profit value;
• wherein each of the first element and the second element are to be placed on a connected pair of first and second resource nodes and the first profit value and the second profit value are based on a relationship between the connected pair of first and second resource nodes.
