I had in mind something like this:
std::priority_queue<int> order;uint max_size = start + max_count; for (uint
gnum=0; gnum < base->numGames; gnum++) {
if (base->treeFilter->Get(gnum) == 0) { continue; }
IndexEntry * ie = base->idx->FetchEntry (gnum);
for (uint gnum=0; gnum < base->numGames; gnum++) { if (filter->Get(gnum)
== 0) { continue; } IndexEntry * ie = FetchEntry (gnum); int
value_sortedby = ie->GetWhiteElo(); order.push(value_sortedby);
if (order.size() > max_size) order.pop();}
std::vector<int> res(max_count);for (int i = max_count -1; i >= 0; i--) res[i]
= order.pop();
This is a sample shorter version of the algorithm in sc_tree_best.Writing
dedicated code without std containers should be faster.However i hadn't made
any speed test.
For the 'interest' value i need some chess help.The actual formula is:interest
= avg_elo + bonus_comment - penalty_old - penalty_earlydraw - penalty_rapid -
penalty_blind
andbonus_comment = 400penalty_old = 20*each_year_old (max 400)penalty_earlydraw
= -250 if < 30 moves; -100 if < 40 movespenalty_rapid = -250penalty_blind = 400
It is a huge improvement versus the old simple avg_elo, but i'm not really
satisfied.Let me now if you have any suggestion.Bye,Fulvio

Hello Fulvio,
it is not that easy if I assume right that you want to have it starting from
the game 20 of the sorted database. Then you need to sort the whole base first.
This takes around 5 to 30 seconds for a large base. Is the user prepared to
wait for this? So we need to discuss the usecases.
