In fact, already when considering k = 10, the Xpress Optimizer took more than 12 hours to exactly solve the instance p5 and explored over 10 million nodes in the search tree.
Everyone who believes there are properties at all, however, agrees that numerically distinct properties can have exactly the same instances without being identical.
Hence, for a given data set exactly the same instances will be selected as seeds for distinct runs of seed finding model.
Note that this is not a mathematically defined class, but rather an intuitive notion of those problems that can be solved exactly, for all the instances of reasonable size, within a reasonable amount of time, using a computer that we can afford.
French beans had to be exactly the right length, for instance, and any that were too long had to be cut short, with the ends fed to livestock.
For instance, exactly the same SNV in the gene melR was found in 16 independent replicate populations of the DOX, ERY, and C50 treatments (table 2 and supplementary table S4, Supplementary Material online).
When the Czechs and Swedes, mostly N.H.L.ers, played the other day, by my count there was exactly one instance of the stultifying dump-and-chase play that dominates offensive style in North American hockey these days: the puck shot from center ice to the corner, followed by either an easy clear back out, or else a stick-jamming battle for the puck.
The alert, he said, "lets the owner know exactly where, for instance, the dog has actually used the bathroom".
But after the first encore, "Cinnamon Girl," ended, someone called out "Cortez!" a moment before Young began to play the song "Cortez the Killer," so that, while the instance didn't exactly qualify as a granted request, it had an air perhaps of considered opinion or, at least, of a shared one.
That makes it hard to produce standardised cells that will all, for instance, make exactly the same nerve cells.
