abstract regarding the imprecise or fuzzy data on the agriculture activities, applying models based on fuzzy data may be useful. in line with this condition this study tries to compare the ability of possiblistic programming approach in developing optimal solution with fuzzy and deterministic programming. to get this objective a data set obtained from 90 farmers of kohgilooye region, gathered i...

In this paper we devise an optimal deterministic algorithm for routing h-relations on-line on an N -input/output multibutterfly. The algorithm, which is obtained by generalizing the circuit-switching techniques of [3], routes any h-relation with messages of X bits in O h(X + logN ) steps in the bit model, and in O hdX= logNe + logN communication steps in the word model. Unlike other recently de...

Cyclical patterns in earnings can arise when contracts between firms and their workers are incomplete, cannot borrow or lend so as to smooth consumption. Effort cycles generate occasional large changes earnings. These transitory, consistent with recent empirical findings.
