(* "best_slices" must be found empirically, taking a wholistic approach since
blanchet@46407
    92
   the ATPs are run in parallel. The "real" component gives the faction of the
blanchet@46409
    93
   time available given to the slice and should add up to 1.0. The first "bool"
blanchet@42723
    94
   component indicates whether the slice's strategy is complete; the "int", the
blanchet@43569
    95
   preferred number of facts to pass; the first "string", the preferred type
blanchet@45521
    96
   system (which should be sound or quasi-sound); the second "string", the
blanchet@46409
    97
   preferred lambda translation scheme; the second "bool", whether uncurried
blanchet@46409
    98
   aliased should be generated; the third "string", extra information to
blanchet@45521
    99
   the prover (e.g., SOS or no SOS).
blanchet@42723
   100
blanchet@42723
   101
   The last slice should be the most "normal" one, because it will get all the
blanchet@43569
   102
   time available if the other slices fail early and also because it is used if
blanchet@43569
