With the increase in biological and medical data it has become necessary for medical and bioinformaticians to have some automated approaches to identify different patterns it their data, so as to predict or have some useful information. Many applications have been described above for genetic algorithm, along with these applications GA has been applied in protein structure prediction, RNA structure prediction and Motif finding. Basic steps of GA are almost same in many applications but it requires expertise, parameters and involves a huge number of randomness and can provide different results in outcomes. Applications of Genetic Algorithm in medicine Oncology Screening tests suggests a valuable chance cancer detection at early stages, which when keep an eye on by proper handling could recover the patient’s survival rate. Developing a non-invasive procedure for the detection of cervical cancer, Duraipandian et al, using colposcopy developed Raman spectra ...
