“…[ 25–27,31 ] A coarser partition Θ c * is a partition { E 1 , …, E p } in which each set E i is the union of one or more Θ * classes of G . The formulae for determining the topological indices using this technique are summarized in the following theorem.Theorem [ 23–25 ] Let G sw = ( G , ( w v , s v ), ( w e , s e )) be a strength‐weighted graph . Let ℰ( G ) = { E 1 , E 2 , .…, E p } be a Θ c * partition of E ( G ), and TI ∈ { W , W e , W ev , Sz v , Sz e , Sz ev , PI , S , Gut , Mo , Mo e , Mo t , w + Mo , w + Mo e , w + Mo t , w * Mo , w * Mo e , w * Mo t }.…”
