Some 20 years ago, the flowchart used to be the ideal tool to represent large chunks of an application. Over the years, the size of flowcharts grew so big to become impractical to handle and engineers started looking elsewhere to find an appropriate model to outline the comp...
Summing up: We call 〈W,(Sw)w∈W,V〉a (Lewis-)spheres model for subjunctive conditionals if and only if all of the conditions above are satisfied. (By means of ‘(Sw)w∈W’ we denote the family of sphere systems for worlds w in W within a given spheres model.) • We call a...
