  Information theory has proven to be a worthwhile tool for investigating the
implications of the Higgs sector in the Next-to-minimal supersymmetric Standard
Model (NMSSM) using Higgs information at the Large Hadron Collider assessed
through the entropy constructed by means of the branching ratios of decay
channels of the Higgs boson. The present article focuses on the parameter space
of supersymmetric extension with an extra term of gauge singlet in light of
various experimental constraints. Our findings show the most preferred values
of $m_0$, $m_{1/2}$, $ A_0$, $ tan\beta$, $\lambda$, $\mu_{eff}$, neutralino
LSP $ m_{\tilde\chi^{0}_{1}}$, lightest chargino $ m_{\tilde\chi^{\pm}_{1}}$,
singlino $ m_{\tilde\chi^{0}_{5}}$, and gluino $ m_{\tilde g}$ to be around
1.93 TeV, 1.78 TeV, $-$3.62 TeV, 27.5, 0.012, 665.7 GeV, 0.74 TeV, 0.79 TeV,
11.24 TeV, and 3.70 TeV, respectively, that is compatible with the relic
density of dark matter.
