On a Feasible-Infeasible Two-Population (FI-2Pop) genetic algorithm for constrained optimization: Distance tracing and no free lunch
TLDR
We explore data-driven methods for gaining insight into the dynamics of a two-population genetic algorithm (GA), which has been effective in tests on constrained optimization problems. Expand

Personalization from incomplete data: what you don't know can hurt
TLDR
We empirically examine the implications of learning from incomplete data in the context of two specific problems: (a) predicting the remainder of any given session will result in a purchase and (b) predicting if a given user will make a purchase at any future session. Based on a comprehensive experiment on user-level clickstream data gathered from 20,000 users' browsing behavior, we demonstrate that models built onuser-centric data outperform model built on site-centricData.

On automated message processing in electronic commerce and work support systems: speech act theory and expressive felicity
TLDR
We compare and contrast three approaches to delivering systems with semantic access: electronic data interchange (EDI), tagged messages, and the development of a formal language for business communication. Expand

Using interactive evolutionary computation (IEC) with validated surrogate fitness functions for redistricting
TLDR
We describe a novel use of evolutionary computation to discover 116 distinct, high quality, legally valid districting plans for the Philadelphia City Council. Expand

Model management : An embedded languages approach
TLDR
We present a technique, called embedded languages, which is a generalization of the EML approach, we believe that this technique can prove extremely useful in implementing desirable features not usually found in existing systems. Expand

Exploring A Two-market Genetic Algorithm
TLDR
The ordinary genetic algorithm may be thought of as conducting a single market in which solutions compete for success, as measured by the fitness funtion. Expand
