In the paper we propose to apply the Invasive Weed Optimization (IWO) algorithm for solving the inverse problem of continuous casting. The investigated task consists in determination of the heat flux in crystallizer and the heat transfer coefficient in the secondary cooling zone on the way of solving the two-phase Stefan problem, describing the discussed process, and minimizing the appropriate functional by using the IWO algorithm. The applied algorithm belongs to the group of artificial intelligence algorithms and is inspired by the extraordinary ability of the colony of weeds for fast growth, quick reproduction and ease of adapting for environmental conditions.

W niniejszej pracy przedstawiamy zastosowanie algorytmu inwazji chwastów IWO (Invasive Weed Optimization algorithm) do rozwiązania odwrotnego zagadnienia odlewania ciągłego. Badany problem polega na wyznaczeniu strumienia ciepła w krystalizatorze oraz współczynnika wnikania ciepła w strefie chłodzenia wtórnego poprzez rozwiązanie dwufazowego zagadnienia Stefana opisującego dyskutowany proces oraz poprzez minimalizację odpowiedniego funkcjonału przy użyciu algorytmu IWO. Zastosowany algorytm należy do grupy algorytmów sztucznej inteligencji i zainspirowany został niezwykłą zdolnością kolonii chwastów do szybkiego wzrostu, reprodukcji oraz łatwości w dostosowaniu się do warunków środowiskowych.
