From: Performance evaluation of the particle swarm optimization algorithm to unambiguously estimate plasma parameters from incoherent scatter radar signals

Probability of convergence (\({P}_{\text{fit\;valid}}\)) and probability of “correct” estimation (\({P}_{\text{correct}}\)) (in percentage) obtained by simulations (dashed lines) with the limited search range of Wu et al. (2015) and (continuous lines) with the full ion composition search range ([0, 1]). Simulations were done at different signal fluctuation percentages (\(\delta (\%)\)) fitting different combinations of known a priori plasma parameters from the plasma line: without a priori information, given \({N}_{e}\), given \({N}_{e}\) and \({T}_{e}/{T}_{i}\), and given \({N}_{e}\) and \({T}_{e}\) parameters
