I am building a optimizer for a game in WPF C#. You start of by adding all the monsters you have and the runes (runes are almost like armor/weapons). You can then choose one of the monsters from a list that you want to optimize. Each monster can equip 6 runes (each rune has a specific slot it can go to, 1-6). The user can then choose what type of runeset it wants (up to 3 diffrent). You need to have 4 or 2 pices (depending on runeset) of the same rune for it be be a runeset. The user can also specify what main type of rune it wants on slot 2,4 and 6 e.x atk% or hp%. After this the user hits a button to optimize.
Here comes my problem, since we want to add all the results in a datagrid so that the user can sort after most possible hp, speed and atk etc. This list will be huge depening on what user has specified in the comboboxes (filtering runeset, type of rune). If no filter is given we are talking about 30^6 results, maybe even more. Ideally the user should be able to do such a big search since it gives the best result, but if that is not possible i can set a limit so the user have to choose some of the filters to cut down the results. My first approach on this was just to make a list add each possible runecombination, and that resultet in out of memory after a few milion searches. Then i tried to save the data to an xml file, this worked but was very slow (did never finish a full search becouse it would take weeks). Then i check up SQLite, and this is where i am now, its decent fast and it might just work. But I am fresh with C# so my code might be very bad and poorly optimized so could need some guidence here to help me out on the code. I dont want to post my full code since its long so I will paste a few important ones and maybe someone can give me some tips on how to optimize this better:
This is the code for the Rune class:
public class Rune
{
public int Rune_ID { get; set; }
public int Rune_Monster { get; set; }
public string Rune_Monster_Name { get; set; }
public string Rune_Set { get; set; }
public int Rune_Slot { get; set; }
public int Rune_Grade { get; set; }
public int Rune_Level { get; set; }
public string Rune_Main_Type { get; set; }
public int Rune_Main_Amount { get; set; }
public string Rune_Innate_Type { get; set; }
public int Rune_Innate_Amount { get; set; }
public string Rune_Sub1_Type { get; set; }
public int Rune_Sub1_Amount { get; set; }
public string Rune_Sub2_Type { get; set; }
public int Rune_Sub2_Amount { get; set; }
public string Rune_Sub3_Type { get; set; }
public int Rune_Sub3_Amount { get; set; }
public string Rune_Sub4_Type { get; set; }
public int Rune_Sub4_Amount { get; set; }
public int Rune_Locked { get; set; }
public int Rune_Sub_HP_F { get; set; }
public int Rune_Sub_HP_P { get; set; }
public int Rune_Sub_Atk_F { get; set; }
public int Rune_Sub_Atk_P { get; set; }
public int Rune_Sub_Def_F { get; set; }
public int Rune_Sub_Def_P { get; set; }
public int Rune_Sub_Spd { get; set; }
public int Rune_Sub_CritRate { get; set; }
public int Rune_Sub_CritDmg { get; set; }
public int Rune_Sub_Res { get; set; }
public int Rune_Sub_Acc { get; set; }
}
Optimize button click:
private void butOptimize_Click(object sender, RoutedEventArgs e)
{
//OptimizeList.Clear();
if (cmbOptMonsters.SelectedItem != null)
{
selectedRuneSets.Clear();
//Makes list of selected runesets
if (cmbOptSet1.SelectedIndex != -1)
selectedRuneSets.Add(cmbOptSet1.SelectedValue.ToString());
if (cmbOptSet2.SelectedIndex != -1)
selectedRuneSets.Add(cmbOptSet2.SelectedValue.ToString());
if (cmbOptSet3.SelectedIndex != -1)
selectedRuneSets.Add(cmbOptSet3.SelectedValue.ToString());
//Makes list of selected runeslots
if (cmbOptSlot2.SelectedIndex != -1)
selectedRuneSlot2 = cmbOptSlot2.SelectedValue.ToString();
if (cmbOptSlot4.SelectedIndex != -1)
selectedRuneSlot4 = cmbOptSlot4.SelectedValue.ToString();
if (cmbOptSlot6.SelectedIndex != -1)
selectedRuneSlot6 = cmbOptSlot6.SelectedValue.ToString();
var selMob = from y in Monsters where y.Monster_Name == cmbOptMonsters.SelectedValue.ToString() select y;
ref2Monster = selMob.First();
worker.RunWorkerAsync();

If anyone need the full code just ask and i can upload the project. Here is a picture of search gui: http://ift.tt/1lXoR6Z
