Abstract
Counting the contribution rate of a world-line formula to Feynman diagrams in theory, we explain the idea how to determine precise combinatorics of Bern-Kosower-like amplitudes derived from a bosonic string theory for -point two-loop Feynman amplitudes. In this connection we also present a method to derive simple and compact world-line forms for the effective action.
