Abstract
Starting with a derivation in the refutation calculus CRIP of Pinto and Dyckhoff we give a constructive algebraic method for determining the values of formulas of intuitionistic propositional logic in a counter-model. The values of compound formulas are computed pointwise from the values on atoms, in contrast to the non-local determination of forcing relations in a Kripke model based on classical reasoning. © Springer-Verlag Berlin Heidelberg 1998.
