11. Problems with continuous variables include constrained problems and multimodal problems. 12. Design problems with continuous variables are normally solved more easily. 13. In a psychological approach, consonance is a continuous variable . 14. It is implicit here that the index of the stochastic process is a continuous variable . 15. "Physiologically, it's a sort of continuous variable , " including people of mixed races, he said. 16. These expected values are found using an integral, for the continuous variables being considered here. 17. In continuous variable systems, the Peres-Horodecki criterion also applies. 18. In the discrete model, the continuous variables are discretized into a set of favorable discrete values. 19. This is the easiest example for continuous variables . 20. In addition, both methods recalculate flow rates, which are continuous variables , whenever a state change occurs.
