 This operation becomes explicit in Dynamic Logic in the form of the program x :=?, called a nondeterministic or wildcard assignment. This is a rather unconventional program, since it is not effective; however, it is quite useful as a descriptive tool....

...operation that produces u[x/a] from u for all possible values aE N. This operation becomes explicit in DL in the form of the program x :=?, called a nondeterministic...square root of y, if it exists, would be the program (1) x :=O; while x 2 <ydo x:=x+1. In DL, such programs are first-class objects on a par with formulas,... | |
