The Building-Block Hypothesis appeals to the notion of problem decomposition and the assembly of solutions from sub-solutions. Accordingly, there have been many varieties of GA test problems with a structure based on buildingblocks. Many of these problems use deceptive fitness functions to model interdependency between the bits within a block. However, very few have any model of interdependency...

While large POS(part-of-speech) annotated corpora play an important role in natural language processing, the annotated corpus requires very high accuracy and consistency. To build such an accurate and consistent corpus, we often use a manual tagging method. But the manual tagging is very labor intensive and expensive. Furthernaore, it is not easy to get consistent results from the humari expert...

Two experiments examined theoretical accounts of why people fail to consider alternative hypotheses in judgments under uncertainty. Experiment 1 found that a majority of participants failed to spontaneously search for information about an alternative hypothesis, even when this required minimal effort. This bias was reduced when a specific alternative was mentioned before search. Experiment 2 sh...

Skepticism of the building block hypothesis (BBH) has previously been expressed on account of the weak theoretical foundations of this hypothesis and the anomalies in the empirical record of the simple genetic algorithm. In this paper we hone in on a more fundamental cause for skepticism—the extraordinary strength of some of the assumptions that undergird the BBH. Specifically, we focus on assu...
