Statistical performance measures for the simulated streamflow with the best DE, GA, SCE, and SaDE estimated parameters of the VIC model

Simulation period	Algorithm	(m³/s)	E_ns	R²	PBIAS
Calibration (mean observed flow = 193 m³/s)	GA	197	0.86	0.92	–2.10
	SCE	198	0.82	0.90	–2.63
	DE	203	0.82	0.91	–5.15
	SaDE	196	0.87	0.93	–1.75
Validation (mean observed flow = 204 m³/s)	GA	189	0.86	0.92	7.28
	SCE	191	0.86	0.93	2.46
	DE	193	0.85	0.93	5.32
	SaDE	207	0.86	0.93	–1.51
