Ezen jegyzetet elektronikus jegyzetnek szánjuk. A lineáris programozási feladatok CPLEX LP kódját sok feladat esetében megadjuk. Ezek a kódok változtatás nélkül futtathatóak, megkönnyítve az eredmények reprodukálását. Ez a módszer a tanulást megkönnyíti, viszont a jegyzet...

Bonus-malus system is an often used risk management tool in the insurance industry, and it is usually modeled with Markov chains. Under mild conditions it can be stated that the bonus-malus system converges to a unique stationary distribution in the long run. The maximum likelihood ratio...
