However both my implementation and yours suffers from an interesting issue: lack of persistence after mutations in certain cases.<br /><br />If you do an update of a node then navigate up and then back down the update is lost. Same for insert ans delete. If you navigate left/right the mutation is correctly reflected since the Context reflects those. <br /><br />The only solution that I see is to persist mutation when moving up and then back down, is to either create new nodes till the root on each up operation (which can be expensive) or create new parent nodes on the fly as we move up. However it is not enough to do this when moving up, because one can use other routes than moving directly up: such as left -> up -> right. The 'up' here is a sibling on the current node's parent. the 'right' is the current node's parent.<br /><br />I'd love to see your thoughts on this.<br /><br />Thanks,<br />MariusMarius Danciuhttps://www.blogger.com/profile/11285466988960120734noreply@blogger.comtag:blogger.com,1999:blog-3049258033565653738.post-87241270413051649552011-10-21T05:19:45.771-07:002011-10-21T05:19:45.771-07:00This comment has been removed by the author.MTavlievahttps://www.blogger.com/profile/16887675209434428004noreply@blogger.comtag:blogger.com,1999:blog-3049258033565653738.post-52634325607488226072011-10-21T05:19:38.698-07:002011-10-21T05:19:38.698-07:00http://www.dmgcc.com/technology.html

I think I can do it in Mathematica, because of its heavy pattern matching. Untested, it might look something like this<br />Adjoin[x_,{}]:={x};<br />Adjoin[x_,{x_,xs___}]:={x,xs}<br />Adjoin[x_,{y_,xs___}]:=Append[xs,Adjoin[x,xs]]<br /><br />Rule 2 says if you see a dup at head of list, don't append. Rule 3 recurses via Mathematica's twisty lack of proper cons, but I hope you can see what I'm trying to express. Y combinator would make it cleaner if longer. When I get back to a machine with an actual installation of Mathematica, I'll test this. Meantime, if you know an expression of this idea in another more mainstream language, I'd be grateful to see it.A Breaking Changehttps://www.blogger.com/profile/00115031720080635093noreply@blogger.comtag:blogger.com,1999:blog-3049258033565653738.post-8237410309331193822011-08-19T14:41:43.332-07:002011-08-19T14:41:43.332-07:00Dear ABC,
Thanks for your comments and question. ...Dear ABC,<br /><br />Thanks for your comments and question. Essentially, by purely syntactic model i mean a generators-relations-style presentation which spans the gamut from traditional Universal Algebra presentations to the more modern grammar + structural equivalence presentation. The key point is that you have a free structure together with bi-directional rewrite rules (relations). This is entirely syntactically representable and constitutes a canonical "symbolic" approach to computing. <br /><br />Best wishes,<br /><br />--gregleithaushttps://www.blogger.com/profile/01069099703796397027noreply@blogger.comtag:blogger.com,1999:blog-3049258033565653738.post-85033702887507065752011-08-19T09:08:40.356-07:002011-08-19T09:08:40.356-07:00Beautiful, and with refreshing precision!
I'm...Beautiful, and with refreshing precision!<br /><br />I'm slightly confused about this statement: "while Set[G] as we know has a purely syntactical model in terms of List[G]"<br /><br />If, by reference to your earlier post, I take "syntactic model" to mean ". . . this solution is entirely syntactic. There is no additional calculation in List( g1, …, gK ) other than to record the elements of the container and their order" -- it is clear how "List[G]" "models" or "implements" Monoid[G], because there are no additional calculations other than to record [existence of] elements and order, i.e., location in the list.<br /><br />And then I look at "we might have a concrete implementation of Set[G] that actually uses List[G] to hold the elements of the collection, but makes certain that with operations that add to the collection, for example, they never allow duplicates"<br /><br />and I see "...with operations...[that] never allow duplicates" and I think "Aha, those are 'additional calculations other than recording existence and location of elements'" <br /><br />and I can't see how List[G] provides a purely syntactic model (or implementation) of Set[G]. The additional duplicate-removing operations and de-ordering operations seem more than syntactic to my eyes. Where have I gone wrong?<br /><br />Thanks again for this great conversation!A Breaking Changehttps://www.blogger.com/profile/00115031720080635093noreply@blogger.comtag:blogger.com,1999:blog-3049258033565653738.post-2488467721754860272011-07-29T14:14:37.390-07:002011-07-29T14:14:37.390-07:00As a musician this reminds me a lot of symmetry an...As a musician this reminds me a lot of symmetry and serialism, as a web dev it reminds me of divs and new html5 symantic elements, as a net admin it reminds me of bitmasking/subnetting, the fact that monads span all of these disciplines reinforces the magnitude of the concept of multiplicity.

Linear types are classical -- in the sense that the negation is involutive.<br /><br />More generally, a logic/type-system can be viewed in terms of a distributive law between a pair of monads. One monad provides the (free) term language, the other provides a notion of collection. The type system shows how to canonically pull the term language through the notion of collection -- in other words how to move from collections of terms to terms of collections, in a canonical fashion. <br /><br />In this set up the terms of collections are the formulae and the map turning them into collections of terms constitutes the semantics of the formula. It says what it means for a term to inhabit a formula.<br /><br />This is all completely general.leithaushttps://www.blogger.com/profile/01069099703796397027noreply@blogger.comtag:blogger.com,1999:blog-3049258033565653738.post-17787216661497564092011-07-23T16:16:19.395-07:002011-07-23T16:16:19.395-07:00I do not see how option, which in a topos is just ...I do not see how option, which in a topos is just (-)~, can be considered as a double negation or, in general, a closure operation.

But there's a lot of work to be done. In any case, we have to abandon the idea of boolean logic as a foundation of everything, and get used to the fact that in types, logic is intuitionistic, and so there.<br /><br />Thanks a lot for this inspiring publication!Vlad Patryshevhttps://www.blogger.com/profile/13466586996802181998noreply@blogger.comtag:blogger.com,1999:blog-3049258033565653738.post-77517566853236774202011-07-23T13:36:29.828-07:002011-07-23T13:36:29.828-07:00@Luc -- thanks!
