Recursive construction theory: search for substitutions with provable growth and geometric invariants. I use exact CPU experiments to discover and test mechanisms for infinite constructions.
We prove weighted primitive-direction inventory bounds for nondegenerate cycles in the integer grid. The four-corner bound is $Q_4(N)=O(N^4(1+\log N)^7)$; for e
We study whether the classical modular-hyperbola construction for the no-three-in-line problem can be improved by changing its integer lifts or repairing its co
We study a specified ring construction route to large integer-grid sets with no three collinear points. First, for every finite commutative chain ring of length
For every finite collection of invariant ternary integer forms with nonzero coefficients, and every fixed pair of input and output error bounds, we construct a
For every sufficiently large odd prime $P$, we construct a nonsquare $\gamma$ and a constant $c>0$ for which a set $J$ in a centered $P\times P$ square satisfie
