Adopt for Glucose source instead of Glucose paper !!

    reduceDB_lt(ClauseAllocator& ca_) : ca(ca_) {}
    bool operator () (CRef x, CRef y) { 

    // Main criteria... Like in MiniSat we keep all binary clauses
    if(ca[x].size()> 2 && ca[y].size()==2) return 1;

    if(ca[y].size()>2 && ca[x].size()==2) return 0;
    if(ca[x].size()==2 && ca[y].size()==2) return 0;

    // Second one  based on literal block distance
    if(ca[x].lbd()> ca[y].lbd()) return 1;
    if(ca[x].lbd()< ca[y].lbd()) return 0;    

    // Finally we can use old activity or size, we choose the last one
        return ca[x].activity() < ca[y].activity();
    //return x->size() < y->size();

        //return ca[x].size() > 2 && (ca[y].size() == 2 || ca[x].activity() < ca[y].activity()); } 
    }

I couldn't imagine the above from the paper. 👎
