Some Health States Are Better Than Others

Some Multiobjective Optimizers are Better than Others

The No-Free-Lunch (NFL) theorems hold for general multiobjective fitness spaces, in the sense that, over a space of problems which is closed under permutation, any two algorithms will produce the same set of multiobjective samples. However, there are salient ways in which NFL does not generally hold in multiobjective optimization. Previously we have shown that a ‘free lunch’ can arise when comp...

Widgets: why are some interventions better than others?

the broader context of service provision, it is important that this does not race ahead of clear prescribing policies, underpinned by pharmocoeconomic considerations. We agree with the respondents that since buprenorphine is more expensive than methadone, the pharmocoeconomic aspects of prescribing need rigorous investigation. Whilst the studies they cite provide preliminary evidence of equipoi...

Normative theories of argumentation: are some norms better than others?

Norms—that is, specifications of what we ought to do—play a critical role in the study of informal argumentation, as they do in studies of judgment, decisionmaking and reasoning more generally. Specifically, they guide a recurring theme: are people rational? Though rules and standards have been central to the study of reasoning, and behavior more generally, there has been little discussion with...

When some are more equal than others.

Some Terms are more Interchangeable than Others

This paper describes the work done by the Information Retrieval Research Group at Océ Technologies B.V., for the Cross-Language Evaluation Forum (CLEF) 2001. We have participated in the Dutch Monolingual task and submitted three runs. In this paper we introduce a new method for relevance computation using two new query operators. This method is meant to be applied to Multilingual Retrieval in t...
