Relative complete recourse

As first-stage feasible solutions in general do not necessarily have a feasible completion in the second-stage due to the implicit constraints in (SUB), the total set of feasible solutions for x is a subset of the first-stage feasible solutions. In this case, the program is called a 2S-MILP without relative complete recourse. For a 2S-MILP with relative complete recourse, each first stage feasible solution x has a feasible completion in the second-stage. 

Having completed the above example, you can appreciate just how complicated a spectrum can become, even with relatively few coupled nuclei. What recourse do we have when a spectrum is so complex that first-order analysis is virtually impossible ... 

An n.m.r. study of the inversion of phosphole derivatives such as (55) has shown that even in complex spin systems a relatively accurate estimate of the inversion barrier may be obtained without recourse to a complete lineshape analysis. In this study, alkyl and aryl substituents did not...
