Figure 5From: Predicting the effectiveness of drug interventions with ‘HIV counseling & testing’ (HCT) on the spread of HIV/AIDS: a theoretical studyPopulation graphs are plotted here for different values of \((u_{1}, u_{2})\). Red trajectories are drawn for the pair of control input values \((u_{1}, u_{2}= (0.0, 0.2))\), whereas black and blue trajectories indicate the graphs for \((u_{1}, u_{2}) = (0.5, 0.4)\) and \((u_{1}, u_{2}) = (0.5, 0.6)\), respectivelyBack to article page
