Numerical abduction: substitutions of 0 and of 1 (initial commit). Analysis of binary plus example.
Arithmetical abduction: accumulate answer before validation.
Numerical abduction: joint abduction loop as in term abduction.
Numerical abduction: substitution of 1 bug fix.
Numeric sort: quantifier violations.
Numerical abduction: candidate substitution bug fix.
Numerical abduction: handle `zparams`. Separation of `bparams` and `zparams` into `b` groups is not used currently.
Numerical sort: eliminate variables with later introduced names first. Test cleanup.
Numerical abduction: fix in substitution of constants (temporary).
Numerical abduction: a different SCA algorithm (initial commit).
During first iteration of main algorithm, instead of solving abduction for other sorts, dissociate other sort variables (replace with non-repeating fresh variables), so that on next iteration, other sorts abduction can find their actual dependencies.
Numerical abduction improved algorithm.
Multisort abduction: explain dissociation.
Numerical sort: expand atom bug fix.
Fixes to quantifier handling. More logging.
Multisort abduction: fix to alien subterm handling -- retain both premise and conclusion part separately.
Do not consider recursive branches at initial iterations of inference in other sorts (i.e. numerical sort).
Abduction validation idea (esp. for other sorts).
