Simple Mail Transfer Protocol (SMPT) is the mail transport protocol used to transfer mail between hosts. In SMTP session, like any protocol, two participants are involved.

An adjoint formulation for the gradient-based optimization of oil–gas compositional reservoir simulation problems is presented. The method is implemented within an automatic differentiation-based compositional flow simulator (Stanford’s Automatic Differentiation-based General Purpose Research Simulator, AD-GPRS). The development of adjoint procedures for general compositional problems is much m...
