On the Problem of Infinity and Gen-Eval in Optimality Theory Paul Hagstrom, MIT November 1993 In the framework of Optimality Theory proposed in Prince & Smolensky (1993), an infinitely large set of candidates is filtered by ranked constraints, simultaneously, to determine the optimal candidate. Although this appears to be computationally impossible given current notions of computability, I suggest here looking at the problem "backwards." Rather than viewing the constraints as ordered filters, we might instead be able to use them as weighted constructors of the optimal candidate. Thus, the finite number of "constructors" (the analog of OT constraints from this vantage point) becomes the upper limit of the computation and not the possibly infinite number of candidate representations. I discuss examples of "constructor analogs" to Onset, HNuc, Fill, Parse, No-Coda, and Coda-Cond as set forth in the OT literature, and show how they might achieve the correct results given a method of "finalizing" most optimal structures to the exclusion of incompatible structures.
