....intractable. In Chapter 5, we review work on the problem of improving the average cost of deciding sentences in languages whose decision problem is in general intractable. First, we examine three sublanguages, in set theory [FOS80, Pol87a] real algebra [CH91, Hon93] and integer linear programming [Dav57, Coo71, Coo72, Sho77, CZ93]. The average case complexity analyses arising in this works tends to be somewhat anecdotal. Several approaches 5 have arisen which give optimistic or at least more definitive average case complexity results. For example, we can search for tiny sublanguages whose decision problem has polynomial ....
....In this chapter, we review work on the problem of improving the average cost of deciding sentences in languages whose decision problem is in general intractable. First, we examine three sublanguages, in set theory ( FOS80] Pol87a] real algebra ( CH91] Hon93] and integer linear programming ([Dav57], Coo71] Coo72] Sho77] CZ93] In reviewing this work we will see that the analysis of the e#ectiveness of heuristics in real algebra and integer linear programming tends toward the anecdotal. Several approaches have arisen which give optimistic results: 1) Search for tiny sublanguages ....

....from some class of functions, rela2 tions and types. It is then natural to focus on the problem of improving on the average cost of decision problems that are in general intractable. In this paper we examine two sublanguages, fragments of set theory [FOS80, Pol87] and integer linear programming [Dav57, Coo71, Coo72, Sho77, CZ93] used in the Davis Schwartz approach to correct program technology. Several ways of dealing with the seeming intractability of these languages have been explored. For example, we can search for tiny sublanguages whose decision problem has polynomial time complexity in the worst case [Pra77, ....
