An apparatus comprising:

• a display;
• a computer system configured to:
• select and apply a transition from a set of first objective enhancing transitions to an initial information integration flow graph based upon how application of each transition impacts a length of a chain of nodes to produce a first set of modified information integration flow graphs that satisfy a first objective;
• select and apply a second transition from the set of first objective transitions and a set of second objective enhancing transitions to the first set of modified information integration flow graphs to produce a second set of modified information integration flow graphs that satisfy the first objective and the second objective;
• and
• identify an information integration flow graph from the first set and the second set having a lowest cost.

A non-transitory tangible computer readable medium comprising code configured to direct a processor to:

• select and apply a transition from a set of first objective enhancing transitions to an initial information integration flow graph based upon how application of each transition impacts a length of a chain of nodes to produce a first set of modified information integration flow graphs that satisfy a first objective;
• select and apply a second transition from the set of first objective transitions and a set of second objective enhancing transitions to the first set of modified information integration flow graphs to produce a second set of modified information integration flow graphs that satisfy the first objective and the second objective;
• and
• identify an information integration flow graph from the first set and the second set having a lowest cost.
