Query: Computing via material topology optimisation   We construct logical gates via topology optimisation (aimed to solve a
station problem of heat conduction) of a conductive material layout. Values of
logical variables are represented high and low values of a temperature at given
sites. Logical functions are implemented via the formation of an optimum layout
of conductive material between the sites with loading conditions. We implement
AND and XOR gates and a one-bit binary half-adder.
