In this paper, a heuristic scheme is used to obtain the numerical solution of the non linear ordinary differential equations (NLODEs). The approximate solutions of the given NLODEs are deduced as a linear combination of some log sigmoid basis functions with unknown parameters. The given NLODEs are converted into equivalent global error minimization problems. Genetic algorithm (GA) and a hybrid ...

Heuristic searches are the most commonly used search methods in the eld of arti cial intelligence. A heuristic provides an estimate of the remaining distance to the goal. With this knowledge, the search algorithms can greatly prune the search tree that has to be explored to nd a solution. Heuristic function is often done by hand using human intuition but can be automated to some extent. An auto...

Mastoiditis is a condition that can occur two weeks after the onset of acute suppurative otitis media. With assistance her daughter, an 86-year-old female patient presented to family medicine outpatient clinic with complaints urinary incontinence and fatigue. Although prevalence media in elderly population varies by country, it generally low, ranging between 0.25 9%. Older patients have otalgia...

This paper addresses a rollon–rolloff waste collection vehicle routing problem which involves large containers that collect huge amounts of waste from construction sites and shopping malls. In this problem, vehicles could only move one container at a time between customers’ locations, a depot, a disposal center, and a recycling center site. Other than a disposal center, a recycling ...

In this paper we propose a hybrid algorithm for the set covering problem (SCP), which combines L-class enumeration, genetic algorithm (GA) and Lagrangean heuristic. The lexicographical enumeration of L-classes in the linear relaxation of SCP ensures optimality of the resulting solution. Both heuristics are used for obtaining the initial approximate solution. The linear subproblems in L-class en...
