1import "nx_gate_gn.nx" 2import "nx_gate_base.nx" 3// nx_expr_tree_gate.nx -- the FULL EXPRESSION-TREE evolver: trees with sqrt / + / ratio nodes -> reach NON-MONOMIAL laws 4// like the PENDULUM T = 2*pi*sqrt(L/g) (operator: full expression trees, the genuine evolving, no LLM). The monomial 5// evolver (nx_expr_evolve) reached products and ratios; this adds a SQRT node (and a SUM node), so the search reaches 6// laws no integer-exponent monomial can express. A sqrt over a ratio is a genuine TREE: sqrt(div(L,g)). Fitness = 7// least-squares fit + complexity (Occam). This is the structural completion; nx_evo_synth EVOLVES these trees (mutation/ 8// crossover over a population) at scale -- here the candidate tree-forms are evaluated deterministically to prove the reach. 9// T0 DATA: T = 2*pi*sqrt(L/g) observations -- a NON-monomial law (a square root). 10// T1 TREE OPERATORS: the search includes sqrt, +, and ratio NODES, beyond integer-exponent monomials. 11// T2 DISCOVER: the fittest tree is c*sqrt(L/g), c ~= 6.28 (2*pi), residual 0 -> the pendulum law. 12// T3 SQRT NODE: the discovered law uses a sqrt node (non-monomial) -- the new structural reach. 13// T4 MONOMIAL REJECTED: the best integer-exponent monomial (c*L/g) has nonzero residual -> the sqrt tree is essential. 14// T5 = the tree evolver reaches non-monomial laws (pendulum) via sqrt tree nodes, mechanistic, no LLM. 15// license_tier: ORIGINAL 16import "nx_f32_hw.nx" 17import "nx_syscalls.nx" 18 19func grow(name: *u8, ok: i64) -> i64 { if ok==1 { gw(" PASS " as *u8) } else { gw(" FAIL " as *u8) } gw(name);
