% 1.76/1.08 Assumed formulas after preprocessing and simplification:
% 1.76/1.08 | (0) ? [v0] : ? [v1] : ( ~ (v1 = 0) & p(v0) = v1 & ! [v2] : ! [v3] : ! [v4] : (v3 = v2 | ~ (p(v4) = v3) | ~ (p(v4) = v2)) & ! [v2] : ! [v3] : (v3 = 0 | ~ (p(v2) = v3)))
% 1.93/1.13 | Instantiating (0) with all_0_0_0, all_0_1_1 yields:
% 1.93/1.13 | (1) ~ (all_0_0_0 = 0) & p(all_0_1_1) = all_0_0_0 & ! [v0] : ! [v1] : ! [v2] : (v1 = v0 | ~ (p(v2) = v1) | ~ (p(v2) = v0)) & ! [v0] : ! [v1] : (v1 = 0 | ~ (p(v0) = v1))
% 1.93/1.13 |
% 1.93/1.13 | Applying alpha-rule on (1) yields:
% 1.93/1.13 | (2) ~ (all_0_0_0 = 0)
% 1.93/1.13 | (3) p(all_0_1_1) = all_0_0_0
% 1.93/1.13 | (4) ! [v0] : ! [v1] : ! [v2] : (v1 = v0 | ~ (p(v2) = v1) | ~ (p(v2) = v0))
% 1.93/1.13 | (5) ! [v0] : ! [v1] : (v1 = 0 | ~ (p(v0) = v1))
% 1.93/1.13 |
% 1.93/1.13 | Instantiating formula (5) with all_0_0_0, all_0_1_1 and discharging atoms p(all_0_1_1) = all_0_0_0, yields:
% 1.93/1.13 | (6) all_0_0_0 = 0
% 1.93/1.13 |
% 1.93/1.13 | Equations (6) can reduce 2 to:
