"True" self-avoiding walk in one dimension

The "true" self-avoiding walk in one dimension is studied via extensive Monte Carlo simulations. For any finite and nonzero value of the repulsion parameter $g$, the asymptotic behavior of the end-to-end distance is characterized by a universal exponent $\nu =0.67\mathrm{}\pm 0.01$, in close agreement with the value $\nu =\frac{2}{3}$ recently predicted by one of us (L.P.).
