Smart Swarms Seek New Ways to Cooperate
Researchers are developing cooperative swarms of tiny robots called smarticles that can collectively perform complex behaviors.
From ACM News
Quantum Algorithms Struggle Against Old Foe: Clever Computers
The quest for "quantum supremacy" – unambiguous proof that a quantum computer does something faster than an ordinary computer – has paradoxically led to a boom...
