Ratio of $\mathrm{D}_{s}$/$\mathrm{D}^0$ measured in 30-50% central Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV (2018 data sample) over $\mathrm{D}_{s}$/$\mathrm{D}^0$ measured in pp collisions at $\sqrt{s}$ = 5.02 TeV (2017 data sample) compared with transport models

Analysis techniques:
- $p_{\mathrm{T}}$ < 1 GeV/$c$: w/o vertexing, PID only (https://alice-notes.web.cern.ch/node/997) only D$^{0}$
- $p_{\mathrm{T}}$ > 1 GeV/$c$: PID + vertexing (https://alice-notes.web.cern.ch/node/905)
- $p_{\mathrm{T}}$ < 3 GeV/$c$ and $p_{\mathrm{T}}$ > 36 GeV/$c$: optimization with Machine Learning for D$_{s}^{+}$
