lookahead

The eight following levels restrict the program ability to lookahead.

The lookahead can also be helpful in deciding when to reduce a rule.

Mark Lawrenson gives his lookahead to the weekend's football action.

The parser has to check the lookahead symbol to tell what to do.

The generator also needs to calculate the expected lookahead sets for each reduce action.

These include a small amount of lookahead, limited discrepancy search, and postprocessing.

It is possible to have more than one level of lookahead carry logic, and this is in fact usually done.

But this minimization is not necessary, and can sometimes create unnecessary lookahead conflicts.

After parameterizing such a rule with a lookahead we have:

This means that the lookahead information can also be used to catch errors, as in the following example:

The game engine featured multiple levels of lookahead to make it more accessible to beginning chess players.

The endgame requires a more analytic approach, sometimes with extensive lookahead.

Some parsers save time and table space by not checking the lookahead symbol in these simple cases.

The mechanism requires that the processes have exploitable lookahead characteristics.

The expected lookahead terminal to apply this rule is noted after the comma.

The lookahead symbol is the 'right-hand context' for the parsing decision.

Each element of the follow set may be a valid lookahead terminal:

This is a great advance over the rate achieved by earlier machines, but it still allows a routine lookahead of only four moves.

A lookahead parser will have around 300 states.

If the lookahead is either of those, the parser shifts them in and advances to state 8 or 9, respectively.

In part two of our lookahead to 2012, our experts give their insights into the technologies sitting on the horizon.

Carry lookahead logic uses the concepts of generating and propagating carries.

Reductions reorganize the most recently parsed things, immediately to the left of the lookahead symbol.

This strategy would later be dubbed "minimax lookahead."

The need for a specific limit on lookahead comes from the large problem graphs in many applications, such as computer chess and computer Go.
