Considering the problem of cognitive radio intelligence optimization, a scheme of cognitive engine is proposed based on the glowworm swarm optimization with t distribution mutation.The bionic principle of firefly algorithm is analyzed.The optimization mechanism is defined by mathematics and a mutation plan is also designed with t distribution. Finally, the simulations are performed in the multi-carrier system. The results show that the algorithm has higher convergence speed and larger objective function value than the basic GA algorithm. Furthermore, the improved algorithm with t distribution mutation has the higher capability of the global optimization than that of the basic GSO algorithm. ©, 2015, Journal of Data Acquisition and Processing.
