What is the difference between the SIMPLE and the SIMPLER algorithms?(

1.	What is the difference between the SIMPLE and the SIMPLER algorithms?(a) No velocity-correction equation(b) No relaxation factor(c) Pressure is directly calculated(d) No pressure-correction equationThis question was addressed to me by my school principal while I was bunking the class.Enquiry is from Incompressible Flows topic in chapter Incompressible Flows & Compressible Flows of Computational Fluid Dynamics
Answer» Right answer is (c) Pressure is directly calculated To explain I would say: The SIMPLE algorithm uses a correction factor for CORRECTING the initial guessed pressure. But, this SIMPLER algorithm does not INVOLVE any GUESS and correction of pressure. It has an equation which can be SOLVED to directly get the pressure VALUES.
