Specifying t-norms based on the value of T(1/2, 1/2)
Yager, Ronald R.; Detyniecki, Marcin; Bouchon-Meunier, Bernadette
We study here the behavior of the t-norms at the point (1/2,1/2). We indicate why this point can be considered as significant in the specification of t-norms. Then, we suggest that the image of this point can be used to classify the t-norms. We consider some usual examples. We also study the case of parameterized t-norms. Finally using the results of this study, we propose a uniform method of computing the parameters. This method allows not only having the same parameter-scale for all the families, but also giving an intuitional sense to the parameters.

Convergence behavior of the (1^+,Lambda) evolution strategy on the ridge functions
Irfan Oyman, A.; Beyer, Hans-Georg; Schwefel, Hans-Paul
The convergence behavior of $\onel$--ES is investigated at parabolic ridge, sharp ridge, and at the general case of the ridge functions. % (for larger values of the parameter $\alpha$).
The progress rate, the distance to the ridge axis, the success rate, and the success probability are used in the analysis.
The strong dependency of the $(1 \! + \! \lambda)$--ES to the initial conditions is shown using parabolic ridge test function when low distances to the ridge axis are
chosen as the start value.
The progress rate curve and the success probability curve of the sharp ridge is explained quite exactly using a simple local model.
Two members of the corridor model family are compared to %the some members of the ridge
function family, % (with large $\alpha$),
and they do not seem to be the limit case of
the ridge function family according to our measures for convergence behavior.

On contrast intensification operators and fuzzy equality relations
Burillo López, Pedro; Fuentes-González, Ramón; González Sotos, León; Marín Martínez, Jesús
The class of contrast intensification operators is formally defined and it's
lattice structure studied. The effect of these operators in the referential
classifications derived from special kinds of fuzzy relations is also determined. Results and examples are presented providing contrast intensification operators which keep quasi-uniformity structures generated
by fuzzy relations while diminishing the fuzziness or the entropy of the relations.
