Strings in Computer

Complex structures are determined for surfaces with $S^2$ and $T^2$ topologies generated by the dynamical triangulation method. For a surface with $S^2$ topology the spacial distribution of the conformal mode is obtained, while for the case of $T^2$ topology the distribution of the moduli parameter is calculated. It is also shown that the network of Feynman diagrams of massive $\phi^3$ scalar theory has a unique complex structure. This gives a numerical justification of the hadronic string model for explaining the n-particle dual amplitude.
