Unification (computer science): awkward line break

Hello EdwardH,

Thank you for improving the formula layout of the article Unification (computer science). However, in the section Unification (computer science)#Substitution, I had intentionally used a table to ease understanding of how substitution application works - each variable should be aligned to the term it gets instantiated to. In my browser (desktop view), that always looked fine, so I wonder what problem was the reason for removing the table. Maybe there is a way to keep the alignment but solving your layout problem?

Best regards

Hi Jochen,

While the layout did make it easier to examine the substitution, I thought that the layout disrupted the natural flow of the text. Do you think that emboldening the substituted terms like this 'f(x, a, g(z), y) yields f(h(a, y), a, g(b), y)', would demonstrate the substitution as well as the table layout?

EdwardH 16:49, 30 January 2014 (UTC)[reply]

This could be a solution, since every 2nd subterm of f happens to be unchanged, so bold/non-bold would happen to give a good contrast in this case. However, my personal taste would still prefer some table solution; what would you think about the following one, looking like indented TeX displaystyle ("$$...$$"), often used in wikipedia math articles (e.g. Lambda calculus#Motivation and below, obtained there by ":<math>...</math>")?

As a first-order example, applying the substitution { x ↦ h(a,y), z ↦ b } to the term

	f(	x	,a,g(	z	),y)
yields
	f(	h(a,y)	,a,g(	b	),y)	.

Or, additionally using boldface according to your suggestion:

	f(	x	,a,g(	z	),y)
yields
	f(	h(a,y)	,a,g(	b	),y)	.

Yes, I think that would work; it can't hurt to copy what other articles are doing. It could do with some changes to the spacing of the punctuation though:

	f(	x	, a, g(	z	), y)
yields
	f(	h(a,y)	, a, g(	b	), y).

That's fine; I'll copy your version into the article. - Jochen Burghardt (talk) 19:59, 1 February 2014 (UTC)[reply]

Wikilinking

Hi, and thanks for your work on the English Wikipedia.

I noticed an article you worked on. Just a short note to point out that we don’t normally link:

dates
years
commonly known geographical terms (including well-known country-names), and
common terms you’d look up in a dictionary (unless significantly technical).

(This even applies for infoboxes.)

Thanks and my best wishes.

Thanks for fixing those and bringing this to my attention. I'll make sure to fix any more in the future. EdwardH (talk) 11:41, 26 February 2014 (UTC)[reply]
