Vienargumenta funkciju ekstrēmu atrašanas skaitliskās metodes

2020

Šajā darbā ir apskatītas vairākas vienargumenta funkciju optimizācijas skaitliskās metodes, lai noskaidrotu, kura metode dod vislabākos rezultātus. Šajā darbā tiks apskatītas tādas metodes kā visaptverošā meklēšanas metode, neierobežotā meklēšanas metode, dihotomijas metode, Fibonači metode, zelta griezuma metode, kā arī salīdzinoši jaunas metodes - “platīna” griezuma metode un meklēšanas algoritms, kas veidots ar haotisku funkciju palīdzību. Šis ir metodiska rakstura darbs.

Ģenētiskais algoritms optimizācijas metodēs

2017

Bakalaura darbā tiek aprakstīts ģenētiskais algoritms, kas ir viens no optimizācijas metožu jaunākajiem un mazāk pazīstamajiem algoritmiem. Teorijas apskatā aplūkots ģenētiskā algoritma konstrukcijas elementi: derīguma (fitness) funkcijas izveide, reproducēšanās, krustošanās un mutāciju operatori. Praktiskajā pielietojumu daļā apskatīti vairāki piemēri (tanī skaitā ceļojošā pārdevēja problēma). Piemēru realizācija veikta ar paketi R .Sniegts neliels metožu salīdzinājums.
