A set of quality criteria is proposed to evaluate the performance of genetic algorithms for optimization. Instead of concentrating solely on the best solutions proposed by the algorithm, the quality criteria also consider the repeatability of the optimization and the coverage of the search space. They are tested by using various parameter settings of a genetic algorithm providing starting struc...

Scheduling problems are NP – Hard combinatorial optimization problems, since many algorithms have been developed which offers new promising insights for solving resource allocation problems. Considering the problems faced in automobile repair shops, who sets the customer due dates of the car based on processing time, jobs already waiting for processing and mechanic available time. Also the work...

This report is a detailed review of the current data on the mechanic and gravitational sensitivity of osteoblasts and osteogenic precursor cells in vitro. It summarizes the numerous responses of cells with an osteoblastic phenotype and osteogenic precursor cells and especially their responses to the alteration of their mechanic or gravitational surroundings. The review also discusses the osteog...

Voluntary Exchange. If an airline mechanic gets paid $30,000 a year, it must be that the mechanic would rather have the money than the leisure time, while the airline would rather have the mechanic than have the money. Another example: apartment rentals. That is, price is bounded below by what the seller will accept: the supply price, and bounded above by what the buyer is willing to pay: the d...

Depictions of scientific development in popular media carry significant influence over the way that the public envisions science as a process and as an institution. One such popular depiction of science is the “Tech Tree,” a common game mechanic in strategy videogames. This mechanic is often problematic, as in its most common form, the tech tree depicts a technologically deterministic view of s...
