Colour-changing beetle inspires algorithm for efficient engineering

An algorithm inspired incidentally a species of beetle changes colour to communicate with its peers and predators solves engineering problems faster than a selection of previous approaches.

The golden tortoise beetle ( Charidotella sexpunctata ) is unusual for the reason that males can change the colour of their wing casings at will between browns, purples, bright orange and gold. Doing so can attract females for mating opportunities and in addition deter predators.

The behaviour inspired Omid Tarkhaneh at the University of Tabriz, Iran, and his colleagues to mimic …
