Conditional symmetry is obtained in a memristive system when the function-based polarity inverse meets the new polarity balance, which produces coexisting oscillations including chaos and other periodic ones. Coexisting bifurcations in two separate spaces were studied, showing an interesting function of amplitude modification in a limited parameter interval. In addition, a cute constant was embedded in the system as a knob to control the coexisting solutions with any desired offset in one dimension. Circuit was designed showing the same dynamics as numerical simulation.
