Design of crossover operator plays a crucial role in Genetic programming (GP). the most studied issues related to crossover operator in GP are: (i) ensuring that crossover operator always produces syntactically valid individuals (ii) improving search efficiency of crossover operator. these issues become crucial when the individuals are represented using linear string representation. this paper aims to introduce postfix GP approach to symbolic regression for solving empirical modeling problems. the main contribution includes (i) a linear string (postfix notation) based genome representation method and stack based evaluation to reduce space-time complexity of GP algorithm (ii) ensuring that sub-tree crossover operator always produces syntactically valid genomes in linear string representation (iii) using semantic information of sub-trees, to be swapped, while designing crossover operator for linear genome representation to provide additional search guidance. the proposed method is tested on two real valued symbolic regression problems. Two different constant creation techniques for Postfix GP, one that explicitly use list of constants and another without use of the list, are presented to evolve useful numeric constants for symbolic regression problems. the results on tested problems show that postfix GP comprised of semantic sub-tree crossover offers a new possibility for efficiently solving empirical modeling problems.

We propose a mathematical model to solve an extension to the mixed-model sequencing problem with work overload minimization (MMSP-W) for production lines with serial workstations and parallel homogeneous processors and regularizing the required workload. We performed a computational experience with a case study of the Nissan engine plant in Barcelona.
Until today the most common technique to debug Java programs is trace debugging. In this work we present two different debugging approaches for Java: declarative debugging, which has its origins in the area of functio...

Developers of preservation repositories need to provide internal audit mechanisms to verify their assertions about how the recommendations outlined in the Open Archival Information System (OAIS) Reference Model are applied. they must also verify the consistent application of preservation policies to boththe digital objects and the preservation system itself. We developed a method for mapping between the OAIS Reference Model functional Model to a data grid implementation, which facilitates such tasks. We have done a preliminary gap analysis to determine the current state of computer task-oriented functions and procedures in support of preservation, and constructed a method for abstracting state transition systems from preservation policies. Our approach facilitates certifying properties of a preservation repository and bridges the gap between computer code and abstract preservation repository standards such as the OAIS Reference Model.
