3rd International math trade starting now!

Recommended Posts

i'm confused now...

example:

i offer one coin called X

and i'm seeking coin A

do i understand it right that a trade only will happen when the persons who offer coin A

are seeking my coin X ???

I think it can get a lot more complicated than that.

person1 has coin A and wants coin X

person2 has coin B and wants coin Y

person3 has coin Y and wants coin A

person4 has coin X and wants coin B

person1 mails to person3

person2 mails to person4

person3 mails to person2

person4 mails to person1

Everybody gets what they wanted, even though it took four people to do it. That's what PSU Fan's fancy algorithm does.

you're exactly right, but luckily you posted the short version. there will actually be as many lines of code as there are coins. While some of the lines will have "DID NOT TRADE" behind them, most will trade. You only have a chance at trading off your one coin for something you ask for. If the algorithm cannot place a coin you want in your hands, in exchange for yours, it WILL NOT trade. That's the safety factor.

aaah ok!

koool...

but everybody will be informed which person to contact!?

thx for the explanation...

Refer to page three of this thread :

Math trade Round 2

It shows who sent what coins. And who received what coins. I assume we will receive something similar from kdv when she runs the math program as well.

Yes, definitely.

And thanks to everyone for stepping up giving explanations while I was out geocaching

OH MY GOODNESS....

just dropped a few on the end of the list almost made it to 600

Including one of these

Is it poor form to list coins that have been purchased but not yet in hand? I'm thinking in particular of the Purple and Black 4 Musketeers.

I would not think so, as long as there is a note explaining that. I have noticed a couple on the list that say "will have in hand by XXXXX" or "purchased and will have soon". For those of us interested in those coins the lister is being fair by letting us know we may have to wait a little to get them.

Can anyone explain what the Google Address Book is, how you access it and find out if you're in it?

It seems to be a very well hidden feature of google

It is a shared spreadsheet set up at google documents. You can contact mousekakat for an invite to be able to view it and add your information.

Yikes--we almost missed this! Neither of us have spent much time on the forums lately, and I saw this posted, but forgot to send our email. Got the email in today, so we'll only have time to get some of our coins listed, but we had great success in the last one!

I see there are a few very nice coins in there I'd like to get, so I just added a few more nice coins to offer sweeter trades. Great to see there were 660 coins on offer when I logged out.

well perhaps there are so many coins it has sent my mac into a spin and all herky jerky - i just corrected an entry which had turned my emu into a platypus! It's a recent coin - you will find pictures and detailed info here

Calling for last orders!

If you still want to join the math trade or add a few more coins, you'd better be quick about it! Tonight at 6pm EST (or rather Midnight CET, which is my local time and hopefully the same as 6pm EST) I will make the list read-only and we can start regrouping (optional) and then defining our want lists. I'll post instructions here right after making the list read-only.

Currently a mindboggling 664 coins have been signed up for this math trade!

Actually anyone that is in the address book can send out an invite.

682 coins now--we added 18 of our traders

Good idea!

LOL avro! I knew you'd say that as there are always some of yours in each trade that I want!

Thanks for adding your coins lindsychris, theres one there I've been chasing a while. Hope I win it!

Almost 700 coins now! a new record, woohoo!

oooh, i'm so nervous.

In half an hour the spreadsheet the coin offer period ends and the spreadsheet will be set to read-only!

Is it just me or did the sheet disappear? Its no longer listed on my google documents. I know it got changed to read only, but i cant even do that LOL Am i missing something somewhere?

Coin offer period closed! We ended up with 34 participants offering a total of 709 coins for trade.

Now the regroup period starts. If you are interested in regrouping coins to make a extra special package so your chances of landing that one very special coin (set), follow the instructions below.

Remember regrouping is optional. If you simply want to trade your coins off one by one as they are listed now, all you need to do is drop me a line saying that you're done regrouping.

When you are satisfied with the way your coins stand, please let me know via email or pm or post in this thread. If everyone finishes with their regrouping early, we can move on to the want lists early.

Please let me know if you have any questions during this period. We'll be open for regrouping until 6pm EST April 30th (coming Wednesday).

Regrouping Instructions

Stage 2: Regrouping

This stage will start after the offer period has closed on April 27th, and ends at 6pm April 30th.

The Regroup Period gives all participants the chance to merge two or more of their coins into a single offer. You can do this to make an offer more attractive to others (and therefore to have a potentially higher chance to get a specifically wanted coin). Remember: if you decide to group two or more coins together, these will only be traded as a complete set (or not at all).

To regroup your offers, send a mail to me through my profile or directly to kdv-at-geocaching.it, containing the ID's and coin descriptions of all coins for each 'coin group' you want to create. Also mention your geocaching.com user name. Please don't use pm's for this - it will help me to keep everything organized in one place.

----------------------------------

Example (this is purely fictitious, personally I am not going to do any regrouping):

Let's say I have seen some VHTF coins that I have set my eye on, and I am afraid that none of my current offers will do the trick to reel in any of those. So I decide to combine my two Mermaid coins into one offer, that might do the trick. And I decide to create a second group to increase my chances of landing big fish even further.

Regrouping for kdv

Group 1

ID 383 Mermaid Swag Copper

ID 384 Mermaid Swag Gold

Group 2

ID 387 Sundial Two Tone

ID 389 GeoNerd v2 kdv Translucent Orange

ID 390 GeoNerd v2 kdv Translucent Blue

---------------------------------------

Use the ID's as listed on the Coin Offers sheet of the final spreadsheet, which is currently read-only and can be found here:

Please let me know if you have any questions about this process. You can also post your questions directly here of course. As soon as everybody is done regrouping (or at the latest at 6pm coming Wednesday) we can start creating our want lists (I will post instructions shortly after this deadline).

I am good and do not need to regroup. Thanks!

made a regroup that is it for know

No regrouping here. All set.

I'm confused enough with this kind of trading so I will not be doing any regrouping this time around. I really don't need to know HOW it works, tho. Perhaps next time I will be braver.

CF30

I don't think I'll mess with anything. Like CF30, I don't want to overcomplicate things.

Email sent with the Regroup info. Ready for the next stage.

I won't be doing any regrouping either.

No regrouping for me.

I did notice a mistake I made on my listings though. Ihave 2 geolicious Sour DNF,nickel listed, one of those is supposed to be black nickel. Can this be fixed? Thank you.

no regrouping for me, thx...

No regrouping, I´ll just trade one for one.

I can now get to the spreadsheet, don´t know how it happened but I´m in.

Everyone that is done regrouping will see their coins listed in bold now. I will mark your coins in bold as soon as you send me your regrouping info or let me know that you will do no regrouping. So once all rows are bold, we are done with the regrouping bit.

Hmmm, took a closer look at my Pennypacker roadtrip and it seems like it is antique gold and NOT antique silver. How do I make that right?

grodan

I've just corrected it for you.

I don't think it was my mac - it was more like spreadsheet overload today 'unresponsive script' then firefox froze up - so I hardly listed anything and i'm a bit scared to go back and look! If I don't reply you'll know why sorry!

You have 4 coins listed right now. If you still want to add the coins that went awry, send me a mail *today* with the details and I'll add them for you (officially the coin adding phase is closed and no other exceptions will be made, unless someone comes up with an even better reason for me to do so!)
