    Abstract:
    I want to bring to the readers' attention the connection between Professor Sieniutycz's "Fermat-type" principle (2000) and the constructal principle, which was published four years earlier in the same journal (1997). This connection generalizes and strengthens the constructal theory of how geometric form (optimized complexity, organization) is generated in macroscopic flow systems. The constructal principle calls for maximizing global performance (objective, purpose, function) subject to global finiteness constraints, in a flow system the architecture of which is free to change. The result of invoking the constructal principle is the architecture of anything that moves-the very configuration (geometry, design, drawing) of the flow system
