A method using invariant imbedding is given for converting Fredholm integral equations with semidegenerate kernels into equivalent initial-value problems that can be solved effectively by analog or digital computers. In this formulation of the initial-value problem the interval length is viewed as an essential variable. A proof is given showing that the solution of the initial-value problem yields a solution of the Fredholm integral equation. Results of test calculations are presented, as well as a FORTRAN program. 43 pp. Refs.

Our mission to help improve policy and decisionmaking through research and analysis is enabled through our core values of quality and objectivity and our unwavering commitment to the highest level of integrity and ethical behavior. To help ensure our research and analysis are rigorous, objective, and nonpartisan, we subject our research publications to a robust and exacting quality-assurance process; avoid both the appearance and reality of financial and other conflicts of interest through staff training, project screening, and a policy of mandatory disclosure; and pursue transparency in our research engagements through our commitment to the open publication of our research findings and recommendations, disclosure of the source of funding of published research, and policies to ensure intellectual independence.
